This patch makes build helper script build.py to use platform.uname for
machine/architecture detection. Visual studio environment when set using
various batch files like vcvars*.bat set PLATFORM environment variable
however VsDevCmd.bat does not set PLATFORM variable.

This reverts commit d9247cc848.
With the Windows tests updated to expect .EXE suffixes. This changed
because shutil.which uses PATHEXT which will contain, amongst others,
"EXE".
Also I noticed the "." in ".exe" was the wildcard dot not literal
dot so I've escaped those.
In build.py we have our own find_executable that looks
a lot like the distutils one that I switched to shutil.which.
This find_executable isn't quite the same as shutil.which
so I've refactored it to call that in the correct way.
Note that the path passed to shutil.which is in the form that
PATH would be, meaning separators are allowed.
```
>>> shutil.which("gcc", path="/home/david.spickett:/bin")
'/bin/gcc'
```
We just need to make sure it doesn't ignore the existing PATH
and normalise the result if it does find the binary.
The .exe extension is automatically added to the binary name
if we are on Windows.

LIT skips various system environment variables while building test
config. It turns out that we require PLATFORM environment variable for
detection of x86 vs Arm windows platform.
This patch adds system environment variable PLATFORM into LIT test
config for detection of win32 Arm platform.

On macOS 11, system libraries which are part of the shared cache
are not present on the filesystem anymore. This causes issues
with build.py, because it fails to link binaries with libSystem
or libc++.
The real issue is that build.py was not passing an SDK to the
compiler. The script accepts an argument for the SDK, but it
is currently unused. This patch just threads the SDK through
to the compile and link steps and this fixes a bunch of Shell
test failures on very recent macOS builds.
LLDB has three major testing strategies: unit tests, tests that exercise
the SB API though dotest.py and what we currently call lit tests. The
later is rather confusing as we're now using lit as the driver for all
three types of tests. As most of this grew organically, the directory
structure in the LLDB repository doesn't really make this clear.
The 'lit' tests are part of the root and among these tests there's a
Unit and Suite folder for the unit and dotest-tests. This layout makes
it impossible to run just the lit tests.
This patch changes the directory layout to match the 3 testing
strategies, each with their own directory and their own configuration
file. This means there are now 3 directories under lit with 3
corresponding targets:
- API (check-lldb-api): Test exercising the SB API.
- Shell (check-lldb-shell): Test exercising command line utilities.
- Unit (check-lldb-unit): Unit tests.
Finally, there's still the `check-lldb` target that runs all three test
suites.
Finally, this also renames the lit folder to `test` to match the LLVM
repository layout.
