This header is not private to the top-level semihosting directory,
so place it in the public include directory.

Perform the cleanup in the FIXME comment in common_semi_gdb_syscall.
Do not modify guest registers until the syscall is complete,
which in the gdbstub case is asynchronous.
In the synchronous non-gdbstub case, use common_semi_set_ret
to set the result. Merge set_swi_errno into common_semi_cb.
Rely on the latter for combined return value / errno setting.

With the exception of hw/core/, the hw/ directory only contains
device models used in system emulation. Semihosting is also used
by user emulation. As a generic feature, move it out of hw/ directory.
