feat(plugins/worker): Support shared inline worker

[NotWoods]

Description

This PR simplifies some of the worker plugin logic by moving duplicate code into a shared function. The new function checks if a URL includes either ?worker or ?sharedworker, then returns a function to build the relevant new Worker(...) function call string.

This also fixes an issue with the plugin where ?sharedworker is ignored for blob URLs.

Additional context

I'm also going to build off this for my rebase in #2494
