Multi thread safe b

Same as #1392 but instead of piggybacking on the Prettier's options, we add our own collected metadata object.

// Old node constructor signature
constructor(ast: NonTerminalNode | TerminalNode, options?: PaserOptions)

// New node constructor signature
constructor(ast: NonTerminalNode | TerminalNode, collected: CollectedMetadata, options?: PaserOptions)

I think I like this option more. I only left a small comment.

I didn't review every single line here, but my understanding is that the three groups of changes are:

• We pass the collectedMetadata in every constructor (that's what affects almost every changed line in this PR).
• That is used instead of the global collections that were used before (only relevant in src/types.d.ts, slangSolidityParser.ts, and SlangNode.ts)
• Some imports now use the .d.ts extension instead of .ts

Assuming that understanding is correct, LGTM.
