Arm micro-architecture dispatch (#344)

Browse Source 
Details:
- Reworked support for ARM hardware detection in bli_cpuid.c to parse 
  the result of a CPUID-like instruction.
- Added a64fx support to bli_gks.c.
- #include arm64 and arm32 family headers from bli_arch_config.h.
- Fix the ordering of the "armsve" and "a64fx" strings in the 
  config_name string array in bli_arch.c. The ordering did not match
  the ordering of the corresponding arch_t values in bli_type_defs.h,
  as it should have all along.
- Added clang support to make_defs.mk in arm64, cortexa53, cortexa57 
  subconfigs.
- Updated arm64 and arm32 families in config_registry.
- Updated docs/HardwareSupport.md to reflect added ARM support.
- Thanks to Dave Love, RuQing Xu, and Devin Matthews for their
  contributions in this PR (#344).
