Support Multipreview annotations in `ModifierMissing` rule

[msfjarvis]

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

Compose now supports providing multiple preview annotations through a "proxy" annotation as documented here, and this currently trips the ModifierMissing lint since it only checks for the Preview annotation.

Describe the solution you'd like

One of these two, depending on complexity

• For each annotation on a function, try to find the annotations present on that annotation class and search for Preview there
• Add a Detekt input to allow providing the names of Multipreview annotations manually

Describe alternatives you've considered

🤷🏼

Additional context

I think we can do something like this here:

• enforce the naming of a multi preview annotation to have "Preview" or "Previews" suffix, via a new rule (these annotations should be pretty clear that they are for previews anyway 🤷 )
• and then filter out the annotations with that suffix in the ModifierMissing rule.

Adding an allowlist of names would also be interesting so that could be done on top of that too.

and then filter out the annotations with that prefix in the ModifierMissing rule.

I'm assuming you meant suffix here?

Other than that, sounds like a plan! Would it be easier to do this internally or can I send a PR?

Haha, yes, I meant suffix 🤦

No worries, I am already on it. I'll do them incrementally but likely ship them altogether in the next release
