Updates to knl kernels and related code.

Details:
- Imported the 24x16 knl sgemm microkernel (and its corresonding spackm
  kernel) from TBLIS and enabled its use in the knl sub-config. Also
  Added sgemm microkernel prototype to bli_kernels_knl.h.
- Updated dgemm and dpackm microkernels from TBLIS, which included an
  important change regarding the offsets array (changed from extern
  declaration to static declaration/definition).
- Activated use of level-1v and -1f zen kernels in skx and knl
  sub-configs.
- Removed some old macros no longer needed in bli_family_skx.h now that
  libmemkind support exists in configure.
- Moved bli_avx512_macros.h to frame/include and adjusted #includes in
  skx and knl kernels accordingly.
- Moved unused kernels in kernels/knl/3 to kernels/knl/3/other
  directory.
- Fixed a minor bug in the 'make' output per compile when verboseness
  is not turned on. The rule-generating function 'make-kernel-rule' was
  previously passing in the name of the config, rather than the name of
  the kernel set returned by get-config-for-kset, which could give
  misleading information to the user when the kconfig_map mapped a
  kernel set to a sub-configuration that did not share the same name.
  (This didn't affect the CFLAGS that were actually used.)
- Updated test/3m4m/Makefile, removing acml targets and renaming the
  remaining targets.
