Fixes #1856

  • switch parser to use scope-manager
    • I was able to delete almost all of the snapshots from parser, because they were (pretty useless and unreviewed) snapshots of the scope tree from every single shared-fixture.
  • Fix up rules:
    • no-unused-vars
      • this exposed so many bugs in the tests themselves - so many unused generic type parameters (function foo<T>() {} and class Foo<T> {}).
    • no-undef
    • no-shadow
      • define an extension rule to handle this arg shadowing, and add an option for ignoring type/value shadowing.
    • no-redeclare
      • define an extension rule to handle function overloads
    • no-use-before-define

BASED ON #1939

BREAKING

This is a big change that will require action from users in the form of:

  • configuring new rules,
  • reconfiguring old rules,
  • handling numerous new reports due to better (correct) coverage,
  • (in some cases) adding the parserOptions.lib to silence some false-positives.

We're going to have to do a 4.0 release v soon due to the optional chain and class property AST changes, so we can hold off on this until then
