I think we shouldn't depend so heavily on SystemTime. Seems weird to tie one of our job types to something that could panic on certain platforms, and users won't be able to sandbox the engine from the OS if this is in place.
Having new(job: NativeJob, timeout: i64) sounds enough for all usecases, and the specific executor can use the provided timeout to schedule the job as it fits.

I don't think we should mention details about SimpleJobExecutor, since every executor can handle the timeout amount in a different way.

This adds non-async implementations of the
setTimeout/setIntervalAPI functions. They are by default registered in the context when registering all APIs fromboa_runtime.This adds a new type of jobs that implement
HostEnqueueTimeoutJob(see https://tc39.es/ecma262/#sec-hostenqueuetimeoutjob).This requires #4141 to be merged first.
