arch-arm: Add aarch64 semihosting support
Add basic support for Arm Semihosting 2.0 simulation calls [1]. These
calls let the guest system call a simulator or debugger to request
OS-like support when running bare metal code.
With the exception of SYS_SYSTEM, this implementation supports all of
the Semihosting 2.0 specification in aarch64.
