Log Message:
-----------
MdePkg/Library/BaseLib: Use PcdControlFlowEnforcementPropertyMask as fixed
Always access PcdControlFlowEnforcementPropertyMask using
FixedPcdGet() in NASM source files and update INFs to correctly
declare that PcdControlFlowEnforcementPropertyMask is always
accessed as a Fixed PCD.
PcdControlFlowEnforcementPropertyMask is declared in MdePkg.dec
in the [PcdsFixedAtBuild] section, so this PCD does not support
any other PCD access types.
This change resolves ld warnings from GCC and CLANGDWARF builds
for relocations in read-only text sections because use of PcdGet()
in NASM source files reads the value into eax from the memory
location of a const global variable that requires a relocation
fixup.
By changing PcdGet() to FixedPcdGet(), eax is loaded with an
immediate value known at build time and no relocation fixups for
PcdControlFlowEnforcementPropertyMask are required.
