Support lacking for Apple Silicon (ARM)

See original GitHub issue

On ARM macOS (all versions), ./build.sh --icu=/opt/homebrew/opt/icu4c/include -j=4 -y --lto-thin leads to:

CMake Error at CMakeLists.txt:47 (message):
    Couldn't detect target processor, try `--arch` argument with build.sh

UPDATE: I now have an Apple silicon device and have begun working on this. Various defines to update, hopefully very little actual code to change but will see.

I’ve started working on updating a few parts of it - I’ve also found other parts where ARM64 code in the wider codebase is windows only - though it’s little bits here and there, very much hoping to be able to complete this task (apple silicon support) but it’s not just changing a handful of conditionals as I’d hoped…

In my offline version the build currently gets to 60% before error-ing out.
