nrf_security: Remove Cracen unused hash funcs/macros

Remove unused macros and functions.
The functions sx_hash_create_(algorithm)
are not used by the PSA driver, only the
sx_hash_create_(engine) are used.

Also the macros SX_HASH_BLOCKSZ_MAX and
SX_HASH_DIGESTSZ_MAX are also unused so
remove them as well.
