x86: gdbstub: add arch-specific funcs to read/write registers

Browse source 
This adds some architecture-specific functions to read/write
registers for the GDB stub. This is in preparation for the actual
introduction of these functions in the core GDB stub code to
avoid breaking the build in between commits.
