Lyude Paul c1f0451ec7 rust: Introduce interrupt module
This introduces a module for dealing with interrupt-disabled contexts,
including the ability to enable and disable interrupts along with the
ability to annotate functions as expecting that IRQs are already
disabled on the local CPU.

Mitchell Levy f73ca66f0d rust: lockdep: Use Pin for all LockClassKey usages
Reintroduce dynamically-allocated LockClassKeys such that they are
automatically (de)registered. Require that all usages of LockClassKeys
ensure that they are Pin'd.

Currently, only `'static` LockClassKeys are supported, so Pin is
redundant. However, it is intended that dynamically-allocated
LockClassKeys will eventually be supported, so using Pin from the outset
will make that change simpler.
