Strong mode requires package_config.json to opt-in packages, so
.dart_tool/package_config.json was added for tests which used .packages
file before.
Certain tests for handling custom foo.packages file were marked
to run only in weak mode (as package_config.json would supersede
custom .packages files).
Finally, certain tests were converted to multi-tests with expected
compile-time errors to reduce number of failing tests (compile-time
error was an expected behavior for those tests, just not reflected
in the test sources).
