test_runner: improve mock timer promisifiers

[Renegade334]

Add some cleanup logic to #setIntervalPromisified and #promisifyTimer to remove the abort listener when the timer either resolves or throws.

Also makes some structural simplifications to both methods. In particular, the previous implementation of #setIntervalPromisified created a single-use anonymous async iterator, before yield*ing from it; this can trivially be converted to yielding from a for await loop.

Needs dont-land-on-v20.x for Promise.withResolvers.
