MdePkg: Move CompilerIntrinsicsLib from ArmPkg
As per the emailed RFC in
https://edk2.groups.io/g/devel/topic/rfc_move/107675828,
this patch moves CompilerIntrinsicsLib from ArmPkg to
MdePkg as this library provides compiler intrinsics, which
are industry standard.
This aligns with the goal of integrating ArmPkg into existing
packages: https://bugzilla.tianocore.org/show_bug.cgi?id=4121.
The newly placed CompilerIntrinsicsLib is added to MdeLibs.dsc.inc
as every DSC that builds ARM/AARCH64 needs this library added. The
old location is removed from every DSC in edk2 in this commit also
to not break bisectability with minimal hoop jumping.
