MdePkg: Avoid hardcoded value for number of Page State Change entries
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4654
The SNP_PAGE_STATE_MAX_ENTRY is based on the number of entries that can
fit in the GHCB shared buffer. As a result, the SNP_PAGE_STATE_CHANGE_INFO
structure maps the full GHCB shared buffer based on the shared buffer size
being 2032 bytes.
Instead of using a hardcoded value for SNP_PAGE_STATE_MAX_ENTRY, use a
build calculated value. Since the SNP_PAGE_STATE_CHANGE_INFO is used as a
mapping, eliminate the hardcoded array size so that the structure can be
used based on any size buffer.
