mrc_cache: Add config MRC_SAVE_HASH_IN_TPM

Use this config to specify whether we want to save a hash of the
MRC_CACHE in the TPM NVRAM space.  Replace all uses of
FSP2_0_USES_TPM_MRC_HASH with MRC_SAVE_HASH_IN_TPM and remove the
FSP2_0_USES_TPM_MRC_HASH config.  Note that TPM1 platforms will not
select MRC_SAVE_HASH_IN_TPM as none of them use FSP2.0 and have
recovery MRC_CACHE.
