[cwksp] Align all allocated "tables" and "aligneds" to 64 bytes (#2546) 
* Perform 64-byte alignment of wksp tables and aligneds internally

* Clean up cwskp_finalize() function to only do two allocs

* Refactor aligned/buffer reservation code, remove ASAN req for alignment reservations

* Change from allocating 128 bytes always to allocating only buffer space as needed for tables/aligned

* Back out aligned/table reservation order restriction

* Add stricter bounds for new/resized wksps, fix comment in zstd_cwksp.h

caecd8c211 Allow user to override ASAN/MSAN detection 
Rename ADDRESS_SANITIZER -> ZSTD_ADDRESS_SANITIZER and same for
MEMORY_SANITIZER. Also set it to 0/1 instead of checking for defined.
This allows the user to override ASAN/MSAN detection for platforms that
don't support it.
