  [libc] Add path to include generated headers for hermetic tests

The generated header files live in the build directory's include path.
When targeting a hermetic build we want to make sure we only use headers
generated by the project itself if availible.

  [libc] Enable the GPU build to build the UnitTest library

The previous patch in D149216 allows us to use the internal `<stdlib.h>`
include for the GPU build. However, we currently don't provide the
memory functions so the header wasn't resolving them. This patch adds
these as entrypoints. They don't cause any entrypoints to be emitted
because they are not implemented, but they provide it in the header so
that we can rely on the test's implementation of them.

Depends on D149216

  [libc] Correctly pass 'CXX_STANDARD' to the packaged GPU build

We need to perform the GPU build separately. The `CXX_STANDARD` option
was not being passed properly.

  Log Message:
  -----------
  [libc] Partially implement `atexit` on the GPU

The `atexit` function controls registering functions to call at the end
of the program. This is difficult to do in general on the GPU because of
the lack of a real mutex implementation. We primarily provide this for
testing where we can explicitly restrict how the `atexit` registration
functions are called. So we simply create a passthrough Mutex to get
past the usage of it as per @sivachandra's suggestion.
