- Updated the thresholds to enter the AVX512 Tiny and SUP codepaths for ZGEMM(on ZEN4). This caters to inputs that perform well on a single-threaded execution(in the Tiny-path), and inputs that scale well with multithreaded-execution(in the SUP path). - Also updated the thresholds to decide ideal threads, based on 'm', 'n' and 'k' values. The thread-setting logic involves determining the number of tiles for computation, and using them to further tune for the optimal number of threads.

For more information on sub-configurations and configuration families in BLIS, please read the Configuration Guide, which can be viewed in markdown-rendered form from the BLIS wiki page.
If you don't have time, or are impatient, take a look at the config_registry
file in the top-level directory of the BLIS distribution. It contains a
grammar-like mapping of configuration names, or families, to sub-configurations,
which may be other families. Keep in mind that the / notation:
<config>: <config>/<name>
means that the kernel set associated with <name> should be made available to
the configuration <config> if <config> is targeted at configure-time.
(Some configurations borrow kernels from other configurations, and this is how
we specify that requirement.)
