pass context through on interrupt handlers

[localyost3000]

Following the instructions @justjake laid out in #84 to add context as an arg to runtime interrupt handlers. This is definitely a useful addition, but not quite to the context-level interrupts I want. Gonna play with this codepath some more to see if I can actually achieve separate interrupts per context. The biggest blocker I know of right now is that interrupt handlers only exist at the runtime level. This means I will need to do something like this.runtime.setInterruptHander((runtime, context) => context === this ? cb(runtime, context) : this.runtime.interruptHandler?.(runtime, context) ?? false) . This leads to a sort of russian nesting doll situation. I would much rather be able to set interrupts per context natively, or have multiple interrupts registered on a runtime

You could use a WeakMap<QuickJSContext, ContextInterruptHandler> to store your per-context interrupt. This kind of indirection is already how per-runtime interrupts are implemented.
