Add minimal AnalysisDriverModel implementation

[davidmorgan]

For #3811, review and merge #3813 first.

Copy resolver_test.dart to analysis_driver_model_test.dart.

Modify all tests to run against the new AnalysisDriverModel instead of the old BuildAssetUriResolver, and add minimal implementation to AnalysisDriverModel to make the tests pass.

Add TODOs where there is functionality not covered by tests that is therefore not added.

This implementation does work for real builds, a local edit to point BuildAssetUriResolver.shared to AnalysisDriverModel is enough to make the benchmarks run. Because there is no caching in the new implementation at all, it's slower :) which gives us a good starting point to add caching.
