rust: timer: wrap QEMUTimer with Opaque<> and express pinning requirements

Timers must be pinned in memory, because modify() stores a pointer to them
in the TimerList. To express this requirement,

rust: timer: wrap QEMUTimer with Opaque<> and express pinning requirements

Timers must be pinned in memory, because modify() stores a pointer to them
in the TimerList. To express this requirement, change init_full() to take
a pinned reference. Because the only way to obtain a Timer is through
Timer::new(), which is unsafe, modify() can assume that the timer it got
was later initialized; and because the initialization takes a Pin<&mut
Timer> modify() can assume that the timer is pinned. In the future the
pinning requirement will be expressed through the pin_init crate instead.

Note that Timer is a bit different from other users of Opaque, in that
it is created in Rust code rather than C code. This is why it has to
use the unsafe constructors provided by Opaque; and in fact Timer::new()
is also unsafe, because it leaves it to the caller to invoke init_full()
before modify(). Without a call to init_full(), modify() will cause a
NULL pointer dereference.

An alternative could be to combine new() + init_full() by returning a
pinned box; however, using a reference makes it easier to express
the requirement that the opaque outlives the timer.

rust: add bindings for timer

Add timer bindings to help handle idiomatic Rust callbacks.

Additionally, wrap QEMUClockType in ClockType binding to avoid unsafe
calls in device code.
