feat: Add import meta

[Brayan-724]

This Fixes #140.

In this pr is implemented the expression import.meta in parser and checker. Also fix some parsing errors related to dynamic import.

Primary features

import.meta is setted to type ImportMeta. import.meta.env is setted to type ImportEnv.

Secondary fix

Before, dynamic import was searching OpenParentheses instead of CloseParentheses.

const _ = import("file");
                       ^ Expected OpenParentheses, ...

Before, dynamic import search for string literals, but do nothing in other cases. After, dynamic import throws error if encounter another thing

This opens an issue. Limit dynamic import to string literals, no variables or expressions

Thanks for review my contribution, your feedback and suggestions are so clear. I'm working on.

All is working, just

• Fixed the interface confusion
• Added the type checking test
• Got a syntax error because the parser saw a statement beginning with import and went to the statement version rather than looking at the token after and realising it was a import.meta. Fixed that in the parser logic 🎉

Ignoring the fuzzing issue which is from separate I was working on. Everything is good to go. Thanks for the change!
