Improved handling of inner class named `$` in JavaTemplate

[MBoegers]

What's changed?

• TypeUtils handle $ better if determing the FQN
• use TypeUtils in rewrite-java*

What's your motivation?

I want the fix the handling of $ as class name. And fixing

• #3623

Have you considered any alternatives or workarounds?

Any additional context

If finished this should enable -https://github.com/openrewrite/rewrite-migrate-java/pull/285
