[Feature Request] Expose AbortController in Workflow sandbox

[lukeramsden]

Is your feature request related to a problem? Please describe.

xstate is a very useful library for implementing state machines in TypeScript codebases. There is a specific feature that is particularly prudent to my usecase - fromPromise. Internally this uses an AbortController as part of it's implementation (see here). In the same vein as #1550, I have a patch locally that exposes AbortController to the vm sandbox, and everything seems to work fine (at least for my usage of xstate currently). From reading the docs this seems like a perfectly safe API to expose to the sandbox.

Describe the solution you'd like

Expose AbortController to the worker workflow sandbox.
