Most of the behavior of LintRuleTest is extracted into a public class
in analyzer_testing, AnalysisRuleTest. A little bit of code is left in
LintRuleTest, so that first-party lint rules can be tested by
registering the first-party lint rules. And those lint rules can
declare the `lintRule` that each is concerned with, rather than the
new `analysisRule` getter.
PubPackageResolutionTest is left as private impl, because I think it
may undergo some changes, and we may be merging more shared code, and
the name may change. A few first-party lint rules have tests that
refer to this class, which is OK.
Other than that, no code or behavior changes are in this CL.
