Quotes API: Add missing Nodes related to Quote ASTs

[jchyb]

There are multiple TODOs in the source code of QuotesImpl.scala suggesting to add more nodes in the future. These include:

• Quote
• Splice
• QuotePattern
• SplicePattern
• TypeBind.apply

TypeBind specifically was mentioned in #11755, but it seems it's used only in QuotePatterns, so adding TypeBind.apply without adding the others would disallow us from even testing whether it properly works.
As we close #11755 by implementing the other missing apply methods, let's track TypeBind.apply here instead.
