lib/stage_cache: Refactor Kconfig options
Add explicit CBMEM_STAGE_CACHE option. Rename
CACHE_RELOCATED_RAMSTAGE_OUTSIDE_CBMEM to TSEG_STAGE_CACHE.
Platforms with SMM_TSEG=y always need to implement
stage_cache_external_region(). It is allowed to return with a
region of size 0 to effectively disable the cache.
There are no provisions in Kconfig to degrade from
TSEG_STAGE_CACHE to CBMEM_STAGE_CACHE.
As a security measure CBMEM_STAGE_CACHE default is changed to
disabled. AGESA platforms without TSEG will experience slower
S3 resume speed unless they explicitly select the option.
