[1/2] arm/edk2-firmware: force debug builds when using Clang

edk2-firmware release builds with clang fail:

MdePkg/Library/UefiMemoryAllocationLib/MemoryAllocationLib.c:142:15:
error: variable 'Status' set but not used [-Werror,-Wunused-but-set-variable]

This is upstream as https://bugzilla.tianocore.org/show_bug.cgi?id=3758,
but until that is resolved we can just force debug builds with clang.

Still broken, v2 incoming.
