[libc++] Unify the benchmarks with the test suite (#101399) 
Instead of building the benchmarks separately via CMake and running them
separately from the test suite, this patch merges the benchmarks into
the test suite and handles both uniformly.

As a result:
- It is now possible to run individual benchmarks like we run tests
  (e.g. using libcxx-lit), which is a huge quality-of-life improvement.

- The benchmarks will be run under exactly the same configuration as
  the rest of the tests, which is a nice simplification. This does
  mean that one has to be careful to enable the desired optimization
  flags when running benchmarks, but that is easy with e.g.
  `libcxx-lit <...> --param optimization=speed`.

- Benchmarks can use the same annotations as the rest of the test
  suite, such as `// UNSUPPORTED` & friends.

When running the tests via `check-cxx`, we only compile the benchmarks
because running them would be too time consuming. This introduces a bit
of complexity in the testing setup, and instead it would be better to
allow passing a --dry-run flag to GoogleBenchmark executables, which is
the topic of https://github.com/google/benchmark/issues/1827.

I am not really satisfied with the layering violation of adding the
%{benchmark_flags} substitution to cmake-bridge, however I believe
this can be improved in the future.

# When bringing up a new cross compiler from scratch, we build

# unable to perform the normal linker checks; this requires a few
# special cases in the CMake files.
#
# Building in an incomplete setup requires setting CMAKE_*_COMPILER_WORKS,
# as CMake fails to probe the compiler. This case also requires
# setting CMAKE_CXX_COMPILER_TARGET, as LLVM's heuristics for setting
# the triple fails when CMake hasn't been able to probe the environment.
# (This is what one has to do when building the initial libunwind/libcxx
