Waker::will_wake: Compare vtable address instead of its content

Optimize will_wake implementation by comparing vtable address instead
of its content.

The existing best practice to avoid false negatives from will_wake is
to define a waker vtable as a static item. That approach continues to
works with the new implementation.

While this potentially changes the observable behaviour, the function is
documented to work on a best-effort basis. The PartialEq impl for
RawWaker remains as it was.
