fix(esp_security): cover the crypto reset coupling in the driver locks

Browse Source 
A peripheral's reset also resets the ones it occupies, so a lock has to cover
both. Gate the ECDSA MPI lock on SOC_ECDSA_USES_MPI rather than the runtime
ecdsa_ll_is_mpi_required() and set that capability on C5, lock the Key Manager
path in esp_key_mgr.c, clean HMAC after its reset, and enable DS before the
primitives its reset covers.
