feat: add abort signal option to invoke function

[dsc8x]

What kind of change does this PR introduce?

Adds support for passing an AbortSignal to function invocations

What is the current behavior?

Functions cannot be aborted. This is bad if you for example use an edge function to fetch input autocompletion results, as you ideally want to cancel all outdated requests if the input changes.

Please link any relevant issues here.

What is the new behavior?

Functions can be cancelled by adding the signal option

We would also need this same exact functionality. Would it be possible to get this PR reviewed and merged?
