Implementing dynamic splices via #${splice} like Scala2-Quill

[deusaquilus]

This is the ProtoQuill equivalent of: zio/zio-quill#1020
It uses a very similar pattern of detecting quote-parts that have a # at the end.
Unlike Scala2-Quill however, the resulting Quote is stored in the runtimeQuotes of the Quoted case class instead of the AST tree. Initially the parser puts into onto the AST tree but then it is extracted and replaced with a QuotationTag (the same as other runtime quotes). This way it fits perfectly into the ProtoQuill compile-time vs runtime paradigm and the ProtoQuill AST is still serializable from the beginning (i.e. from quotation onward vs Scala2-Quill which is not because it stores Dynamic and Lift values directly in the tree).
