1959032 - Rework life cycle of JS::Dispatchable

Status: NEW

(Core :: JavaScript Engine, task, P3)

Description

[Yulia Startsev [:yulia]]

As part of atomics.waitAsync, we had extensive discussions regarding the life cycle of JS::Dispatchable. The current lifecycle relies on JS::Dispatchables deleting themselves [1]][2]. waitAsync added an additional deletion related to clearing undispatched classes.

A better pattern here would be to use uniqueptrs or a similar mechanism, and to make clear the ownership relationship between JS::Dispatchables, the embedding, and the engine. A high level description of the plan can be found here.
