[XRay][compiler-rt] FDR Mode: Allow multiple runs
Summary:
Fix a bug in FDR mode which didn't allow for re-initialising the logging
in the same process. This change ensures that:
- When we flush the FDR mode logging, that the state of the logging
implementation is `XRAY_LOG_UNINITIALIZED`.
- Fix up the thread-local initialisation to use aligned storage and
`pthread_getspecific` as well as `pthread_setspecific` for the
thread-specific data.
- Actually use the pointer provided to the thread-exit cleanup handling,
instead of assuming that the thread has thread-local data associated
with it, and reaching at thread-exit time.
In this change we also have an explicit test for two consecutive
sessions for FDR mode tracing, and ensuring both sessions succeed.
