gdbstub: Adjust gdb_do_syscall to only use uint32_t and uint64_t
...
Pass %x as uint32_t and %lx as uint64_t; pass the address
of %s as uint64_t and the length as uint32_t.
Add casts in semihosting/syscalls.c from target_ulong to
uint64_t; add casts from int to uint32_t for clarity.

This function is unused, except to implement gdb_do_syscall.

gdbstub: split out softmmu/user specifics for syscall handling
...
Most of the syscall code is config agnostic aside from the size of
target_ulong. In preparation for the next patch move the final bits
of specialisation into the appropriate user and softmmu helpers.

gdbstub: move syscall handling to new file
...
Our GDB syscall support is the last chunk of code that needs target
specific support so move it to a new file. We take the opportunity to
move the syscall state into its own singleton instance and add in a
few helpers for the main gdbstub to interact with the module.
I also moved the gdb_exit() declaration into syscalls.h as it feels
pretty related and most of the callers of it treat it as such.
