MdePkg/CompilerIntrinsicsLib: Fix IA32 with VS202x
CompilerIntrinsicsLib is causing a #UD when used in IA32 mode.
This was tracked back to memcpy using size_t, which locally
defined in the file as __int64. When compiling for IA32 target,
this results in the memcpy interpreting 64 bits from the
calling convention instead of the 32 bits that were passed.
Update the local size_t defines to use UINTN. This matches
the functionality from CryptoPkg's Intrinsic functions.
Add CompilerIntrinsics to IA32/X64 component so it is complied
as part of CI.
Add size_t as ECC check exclusion to MdePkg.ci.yaml.
