rust: irq: add support for non-threaded IRQs and handlers
This patch adds support for non-threaded IRQs and handlers through
irq::Registration and the irq::Handler trait.
Registering an irq is dependent upon having a IrqRequest that was
previously allocated by a given device. This will be introduced in
subsequent patches.
