Flag TORCH_SDT_SEMAPHORE as being name resovable (#141191)

Browse Source 
Summary:
Mirroring changes in D64604573, it appears this code in libcaffe2 is
mostly a copy of folly's one. Copy of the original diff summary:

This particular inline assembly use cannot be converted to a constraint template parameter (until llvm 18 / gcc 14), as there is no way (until those versions) to specify that a non-pic relocation is needed when compiling under pic.  This inline assembly requires a non-pic relocation because it is being written to the .notes section, which is non .text.
