Adds a possibility to access the first Token of a SyntaxNode.

Discussed in https://github.com/MikePopoloski/slang/discussions/898

As discussed, there would be a need to write-access in a generic fashion the first token of any SyntaxNode.

I am willing to try and implement it myself.

In order to not disrupt the current features would be to:

• Create a ReferenceTokenOrSyntax object (or another name) which would hold the reference or a pointer to a Token or a Syntax.
• Update gen_syntax.py to implement the getChild version which would return the ReferenceTokenOrSyntax
• Implement/Update the getFirstChild and getLastChild functions.

Could I have a confirmation that this is the right approach ?

Yes, that sounds right. I think you'll want it to be a pointer, so TokenPtrOrSyntax probably.

Ok, thanks for the pointers. I may not have much time in the next week, but I'll have a look into this 🙂
