1713498c0d rust: move hwcore::sysbus to system crate
This inverts the dependency from hwcore to system, replacing it with
a dependency from system to hwcore.  It also matches how hw/core/sysbus.h
is part of the system-sys crate, and hw/core/sysbus.c is part of system_ss
on the C side.

This fixes a linker error in hwcore integration tests on msys2.

c899071b5a rust: move binding generation to bindings/
Move raw FFI bindings generation to separate crates.  This makes it
possible to reuse bindgen declarations for a header file in its
dependencies (this was not the case before this change), while keeping
multiple -sys crates to avoid rebuilding all the code whenever
something changes.

Because the -sys crates are generated in dependency order, this also
enforces that the crates are organized in something that resembles
the dependencies between C headers.

The meson.build for rust-safe crates becomes simpler, and it should be
possible in the future to let Meson's cargo support handle most of it.

d97c8037bf rust/system: Stop exposing bogus DEVICE_NATIVE_ENDIAN symbol
We want to remove the bogus DEVICE_NATIVE_ENDIAN definition
(by only having it explicit, either big or little one). Stop
exposing it to rust devices to avoid it spreading further.

80a3c9c01a rust: remove useless glib_sys bindings
The definition of types needed for g_autolist(), g_autoslist(),
g_autoqueue() need the imports for GList, GSList and GQueue
to appear everything.  Rust code is never going to see those,
since they are not used in structs.  Block the types from
appearing in the bindings.
