vc/edk2-stable202302: Remove FSPM_ARCH_UPD config guard

This commit removes config guard around FSPM_ARCH_UPD from the
FspApi.h header file. This change is done to ensure
that this header file can be used with both x86_32 and x86_64
architectures and also with different FSP specification versions.

The following modifications are made:
- Removes PLATFORM_USES_FSP2_X86_32 config guard around
  FSPM_ARCH_UPD, this was added to isolate the structure from
  x64 build. This is not really required since the x64 build uses
  FSP2.4 structures.

BUG=b:343428206
TEST=Verified x86_32 and x86_64 builds on Meteor Lake board (Rex)
