Replace getJetTypeFqName with fqNameOrNull extension

[3flex]

Closes #3605

This extension isn't a 1:1 replacement for getJetTypeFqName since that function has some extra logic built in to print type arguments, but that isn't used by any rules so this replacement should do the trick.

It returns the FqName instead of String like the old function did, but that might actually be more useful depending on how it's used.

I've also found the property nameIfStandardType was also imported from the js package so I've refactored to avoid its use.
