Ref#1856

This is an alternate approach to#1533.
Instead of just extending bits and pieces, bring the entire codebase in, clean it up and rebuild it to have native support for TS types.

I found that trying to make the types work was a complete pain because we need a custom typed version of each class anyway.
I figure that we support our own set of JS on top of whateslint-scope supports, so it's probably better we maintain the entire stack so we don't do any hacky extension things.

We don't want to get into a position where the base package adds handling we weren't expecting.

WIP

• forkeslint-scope,
  • add types,
  • restructure the code for better type safety,
  • rename everything and add accessibility / readonly modifiers,
  • delete deprecated functionality as I could,
    • https://eslint.org/docs/developer-guide/scope-manager-interface
• fork theeslint-scope tests,
  • added types
  • restructured the code for better type safety
  • deleted based on deprecated removals above
• support:
  • ClassProperty
  • Decorator
  • OptionalMemberExpression
  • OptionalCallExpression
  • TSAbstractClassProperty
  • TSAbstractMethodDefinition
  • TSAsExpression
  • TSDeclareFunction
  • TSExportAssignment
  • TSImportEqualsDeclaration
  • TSInterfaceDeclaration
  • TSMappedType
  • TSModuleDeclaration (will need their own scope)
  • TSParameterProperty
  • TSTypeAliasDeclaration
  • TSTypeAssertion
  • TSTypeParameter
  • TSTypePredicate
  • TSEnumDeclaration (will need their own scope)
• prevent invalid identifiers in type locations from creating references
  • property signature name
    • TSPropertySignature
  • function/method/call/construct signature parameter names
    • TSCallSignatureDeclaration
    • TSConstructorType
    • TSConstructSignatureDeclaration
    • TSEmptyBodyFunctionExpression
    • TSFunctionType
    • TSMethodSignature
  • index signature parameter name
    • TSIndexSignature
• support type locations on non-type nodes
  • class implements
  • class extends type parameter instantiation
  • variable types
  • parameter types
  • function type parameter decls
  • call type parameter instantiation
  • treat normal imports as type/values, treat type only imports as types.
• update to handle our v3.0.0 changes

BASED ON#2230

Must be retargeted before merging
