Ard Biesheuvel ecb1d67775 BaseTools/tools_def CLANGDWARF: Always use -Oz in RELEASE mode 
GCC5 and CLANGDWARF for IA32/X64 use -Os or -Oz as the optimization
level, which agressively optimizes for the smallest possible object
code.

On AARCH64, RISCV64 and ARM, we use -O3 instead, which results in
considerable image bloat, to the point where the Raspberry Pi 4 build in
edk2-platforms does not even build with -D SECURE_BOOT_ENABLE.

So let's align CLANGDWARF across all architectures, and use -Oz
throughout.

Note that O3 is still used for the linker, which build in LTO mode and
therefore performs some code generation as well. This is deliberate: LLD
does not support the Os/Oz optimization levels at all, and using Oz for
the compile pass is sufficient to reduce the code size substantially.
