The LoongArch64 firmware build does not link against libgcc, so provide the helper from CompilerIntrinsicsLib. Implement __ashlti3 using the LoongArch64 ABI: the low and high 64-bit halves are passed in $a0 and $a1, the shift count is passed in $a2, and the result is returned in $a0 and $a1.

This commit removes ARM32 code from CompilerIntrinsicsLib.

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.
