[submodule] Bump fbgemm to latest (#158210)

Browse Source 
Merge the recent commits of FBGEMM and remove unnecessary CMake code.
Specifically, we
1. enable `fbgemm_autovec` since the target is now correctly handled.
2. remove option `USE_FAKELOWP` which is not used.
3. remove `CAFFE2_COMPILER_SUPPORTS_AVX512_EXTENSIONS` check.
