The Arm Semihosting layer currently assumes that the guest application
shares STDIO with gem5. This makes it hard to distinguish application
output from gem5's output and makes it impossible to redirect STDIN
when running in interactive mode. Add support for custom STDIO
redirection when instantiating the Semihosting model.

The semihosting component currently issues non-secure memory accesses
using the standard port proxy. This doesn't work when the guest is
running in secure state.

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.
