Some behavior changes:
* `-t=d` is removed. Use `-t d` instead.
* one-dash long options like `-all` are supported. Use `--all` instead.
* `--all=0` or `--all=false` cannot be used. (Note: `--all` is silently ignored anyway)
* `--help-list` is removed. This is a `cl::` specific option.
Nobody is likely leveraging any of the above.
Advantages:
* `-t` diagnostic gets improved.
* in the absence of `HideUnrelatedOptions`, `--help` will not list unrelated options if linking against libLLVM-13git.so or linker GC is not used.
* Decrease the probability of cl::opt collision if we do decide to support multiplexing
Note: because the tool is so simple, used more for forensics instead of a building
tool, and its long options are unlikely used in one-dash form, I just drop the
one-dash form in this patch.

This patch tidies up the llvm-strings testing by:
1. Adding comments to every test.
2. Getting rid of canned input files, and having the tests generate
them on the fly (this makes the tests self-contained).
3. Adding missing test coverage.
4. Renaming some tests that weren't clear as to their purpose.
5. Adding extra checking of various cases, formatting etc.
6. Removing a test that didn't seem to have any useful purpose for
testing llvm-strings.

Many LLVM-based tools already support response files (i.e. files
containing a list of options, specified with '@'). This change simply
updates the documentation and help text for some of these tools to
include it. I haven't attempted to fix all tools, just a selection that
I am interested in.
I've taken the opportunity to add some tests for --help behaviour, where
they were missing. We could expand these tests, but I don't think that's
within scope of this patch.
This fixes https://bugs.llvm.org/show_bug.cgi?id=42233 and
