Remove NaCl/arm target support

Remove NaCl/arm target support

NaCl has been deprecated:

https://developer.chrome.com/docs/native-client/migration/

It is now in the process of being removed from llvm:

https://github.com/llvm/llvm-project/pull/133661

Remove NaCl/arm target support from bfd, binutils, gas and ld.
