Argyrios Kyrtzidis 57c1f72cc3 [Parse] Optimize syntax parsing: Make ParsedRawSyntaxNode a POD type
This eliminates the overhead of ParsedRawSyntaxNode needing to do memory management.
If ParsedRawSyntaxNode needs to point to some data the memory is allocated from a bump allocator.

There are also some improvements on how the ParsedSyntaxBuilders work.
