Refactor goja runtime value parsing out of page.waitForFunction promise

[ankur22]

What

Refactor the parsing of the option out of the promise and into the mapping layer for page.waitForFunction.

Why

This will help avoid a scenario where more than one off main goja thread goroutine (i.e. promise) is ran concurrently which could try to access the goja runtime concurrently and cause a panic.
