ARM: Support CLANG CFIb4/arm32-cfi
Support Control Flow Integrity (CFI) when compiling with
CLANG.
In the as-of-writing LLVM CLANG implementation (v17)
the 32-bit ARM platform is supported by the generic CFI
implementation, which isn't tailored specifically for ARM32
but works well enough to enable the feature.
