Expand ScopeContext into the single place that manages resolver
name-scope transitions, and migrate visitors to use it directly.
ScopeContext now:
- Owns the current name scope and handles push/pop via withScope().
- Provides focused helpers for common resolver scopes:
- withLocalScope(), withInstanceScope(), withExtensionScope()
- withTypeParameterScope() and withTypeParameterList()
- withFormalParameterScope()
- withConstructorInitializerScope() and withPrimaryParameterScope()
- withDocImportScope() for documentation comment resolution
- Renames walkMixinDeclarationScopes() to visitMixinDeclaration() and routes
mixin traversal through the shared helper.
Update ResolutionVisitor, ScopeResolverVisitor, and ReferenceResolver
to:
- Remove temporary routing getters/methods and ad-hoc try/finally scope
management.
- Use the new ScopeContext helpers for consistent scoping across declarations,
function bodies, and DeCo/primary-constructor-related initializer contexts.
- Reduce duplicated scope wiring and keep scope behavior localized for easier
future evolution.
