compiler/next: string and numeric literals

This PR adds uAST classes for:

  • StringLiteral
  • BytesLiteral
  • CStringLiteral
  • IntLiteral
  • UintLiteral
  • RealLiteral
  • ImagLiteral

These are all subclasses of Literal. The idea here is that since we
already have polymorphism from the AST node inheritance we don't need to
have a union also for the types. Currently we have a different uAST type
for each type of literal (type as in int uint string etc).
Originally, I had been thinking this effort would use the compiler/ifa
code right away, but since simply representing the literal values does
not require any computation be done on them, I opted not to do that yet.
I think that ifa code will still be important when evaluating param
expressions.

  • [x] make test-libchplcomp passes
  • [x] full local testing
