rust: id_pool: do not immediately acquire new ids
When Rust Binder assigns a new ID, it performs various fallible
operations before it "commits" to actually using the new ID. To support
this pattern, change acquire_next_id() so that it does not immediately
call set_bit(), but instead returns an object that may be used to call
set_bit() later.
The UnusedId type holds a exclusive reference to the IdPool, so it's
guaranteed that nobody else can call find_unused_id() while the UnusedId
object is live.
