Setting up all the infrastructure for BGEMM support in OpenBLAS, hopefully I found all the right places.

Derived mostly from the previous work done in https://github.com/OpenMathLib/OpenBLAS/pull/5287

Update FAQ

Fix some hyperthreading errors.

When there are multiple NUMA nodes and hyper-threading causes adjacent logical cores to share a physical core (e.g., common -> avail[i] = 0x5555555555555555UL), the numa_mapping function should not use a bitmask for filtering, as this would lead to redundant masking with the subsequent local_cpu_map function.
