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.
