Remove the remaining references to LLDB_CAPTURE_REPRODUCER. I removed
the functionality in an earlier commit but forgot that there was a
corresponding test and logic to unset it in our test suite.
lit has grown a feature where it stores the runtimes of all tests.
Normally, these times should be stored in the build directory, but
because our API tests have set test_exec_root to point to the source
tree, it has ended up polluting our checkout and led to the
.lit_test_times.txt being committed to the repository.
Delete this file, and adjust the exec root of API tests. I've also
needed to adjust the root of Shell tests, in order to avoid the two
overlapping.
Make the API, Shell and Unit tests independent lit test suites. This
allows us to specify different dependencies and skip rebuilding all the
unit test (which is particularly expensive) when running check-lldb-api
or check-lldb-shell.
This does not change the autogenerated targets such as
check-lldb-shell-driver or the top level check-lldb target, which all
continue to work as before.

This variable is used to reducing the likelihood of hitting module cache
issues in CI where different branches can potentially run on the same
machine.
Replace the dotest command line options and various cmake variables,
which are used for passing the locations of llvm tools to the API tests
with a single variable, which points to the directory these tools are
placed in. Besides reducing repetition, this also makes things more
similar to how "normal" llvm tests are configured.

Test runs log some of their output to files inside the LLDB session dir. This
session dir is shared between all tests, so all the tests have to make sure they
choose a unique file name inside that directory. We currently choose by default
`<test-class-name>-<test-method-name>` as the log file name. However, that means
that if not every test class in the test suite has a unique class name, then we
end up with a race condition as two tests will try to write to the same log
file.
I already tried in D83767 changing the format to use the test file basename
instead (which we already require to be unique for some other functionality),
but it seems the code for getting the basename didn't work on Windows.
This patch instead just changes that dotest stores the log files in the build
directory for the current test. We know that directory is unique for this test,
so no need to generate some unique file name now. Also removes all the
environment vars and parameters related to the now unused session dir.
The new log paths now look like this for a failure in 'TestCppOperators`:
```
./lldb-test-build.noindex/lang/cpp/operators/TestCppOperators.test_dwarf/Failure.log
./lldb-test-build.noindex/lang/cpp/operators/TestCppOperators.test_dsym/Failure.log
./lldb-test-build.noindex/lang/cpp/operators/TestCppOperators.test_gmodules/Failure.log
```

The new FreeBSDRemote plugin has reached feature parity on i386
and amd64 targets. Use it by default on these architectures, while
allowing the use of the legacy plugin via FREEBSD_LEGACY_PLUGIN envvar.
Revisit the method of switching plugins. Apparently, the return value
of PlatformFreeBSD::CanDebugProcess() is what really decides whether
the legacy or the new plugin is used.
Update the test status. Reenable the tests that were previously
disabled on FreeBSD and do not cause hangs or are irrelevant to FreeBSD.
Mark all tests that fail reliably as expectedFailure. For now, tests
that are flaky (i.e. produce unstable results) are left enabled
and cause unpredictable test failures.

LIT uses a model where the test suite is configurable trough a
lit.site.cfg file. Most of the time we use the lit.site.cfg with values
that match the current build configuration, generated by CMake.
Nothing prevents you from running the test suite with a different
configuration, either by overriding some of these values from the
command line, or by passing a different lit.site.cfg.
The latter is currently tedious. Many configuration values are optional
but they still need to be set because lit.cfg.py is accessing them
directly. This patch changes the code to use getattr to return the
attribute if it exists. This makes it possible to specify a minimal
lit.site.cfg with only the mandatory/desired configuration values.

The Python 3 interpreter in Xcode has a relative RPATH and dyld fails to
load it when we copy it into the build directory.
This patch adds an additional check that the copied binary can be
executed. If it doesn't, we assume we're dealing with the Xcode python
interpreter and return the path to the real executable. That is
sufficient for the sanitizers because only system binaries need to be
copied to work around SIP.
This patch also moves all that logic out of LLDBTest and into the lit
configuration so that it's executed only once per test run, instead of
once for every test. Although I didn't benchmark the difference this
should result in a mild speedup.

These tests are flaky on the reproducer bot. I suspect it has something
to do with the module cache. Skipping the whole category while I
investigate the issue.
[intel-pt] Improve the way the test determines whether to run
- Now I'm creating a default value for the new test parameter
- I fixed a small mistake in the skipping logic of the test
... I forgot to clear the cmake cache when testing my diff
Summary:
@labath raised a concern on the way I was skipping this test. I think that was
fair and I found a better way.
Now I'm skipping if the CMAKE flag LLDB_BUILD_INTEL_PT is false.
I added an enabled_plugins entry in the dotest configuration, which gets
set by lit or lldb-dotest. The only available plugin right now is
'intel-pt', but I imagine it will be useful in the future for other
kinds of plugins that get determined at configuration time. I didn't
want to add a new argument option --enable-intel-pt or something or the
sort, as it wouldn't be useful for other cases.

Make it possible to capture reproducers from the API test suite. Given
the symmetry between capture and replay, this patch also adds the
necessary code for replay. For now this is a NO-OP until the
corresponding reproducer instrumentation changes land.

Summary: Moves lldbsuite tests to lldb/test/API.
This is a largely mechanical change, moved with the following steps:
```
rm lldb/test/API/testcases
mkdir -p lldb/test/API/{test_runner/test,tools/lldb-{server,vscode}}
mv lldb/packages/Python/lldbsuite/test/test_runner/test lldb/test/API/test_runner
for d in $(find lldb/packages/Python/lldbsuite/test/* -maxdepth 0 -type d | egrep -v "make|plugins|test_runner|tools"); do mv $d lldb/test/API; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-vscode -maxdepth 1 -mindepth 1 | grep -v ".py"); do mv $d lldb/test/API/tools/lldb-vscode; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-server -maxdepth 1 -mindepth 1 | egrep -v "gdbremote_testcase.py|lldbgdbserverutils.py|socket_packet_pump.py"); do mv $d lldb/test/API/tools/lldb-server; done
```
lldb/packages/Python/lldbsuite/__init__.py and lldb/test/API/lit.cfg.py were also updated with the new directory structure.

Rather than serializing every argument through LLDB_TEST_COMMON_ARGS, we
can pass some of them directly using their CMake variable. Although this
does introduce some code duplication between lit's site config and the
lldb-dotest utility, it also means that it becomes easier to override
these values (WIP).
