Use FileSource backed by analyzer_testing resources instead of the test-only Source implementations in analyzer tests. Update the lightweight TestAnalysisContext to receive a ResourceProviderMixin and install a URI resolver that produces real FileSource instances for the dart: and package: URIs used by mock SDK elements. Convert scanner, diagnostic, options, constant, type system, and workspace tests to create sources from in-memory files. Remove the remaining Source mock helpers, including TestSource, TestSourceWithUri, local Source mocks, and the unused TestTypeProvider. This keeps test sources closer to production Source behavior and avoids partial mock implementations that rely on noSuchMethod stubs.
