gdbstub: Replace GET_REG*() macros with gdb_get_reg*() functions

This avoids polluting the global namespace with a non-prefixed macro and
makes it obvious in the call sites that we return.

Semi-automatic conversion using, e.g.,
 sed -i 's/GET_REGL(/return gdb_get_regl(mem_buf, /g' target-*/gdbstub.c
followed by manual tweaking for sparc's GET_REGA() and Coding Style.
