[CFE] Add "strong" tests of the constant evaluator

This increases our "local" coverage of the constant evaluator.
Run with something like
`pkg/front_end/test/fasta/strong_tester.dart -DupdateExpectations=true -DstressConstantEvaluator=true -DskipVm=true`
there is now almost coverage of everything (or a comment in the code
suggests that the path is probably unreachable).

Note that
`out/ReleaseX64/dart pkg/front_end/test/vm_service_coverage_constant_evaluator.dart pkg/front_end/test/fasta/strong_tester.dart -DupdateExpectations=true -DstressConstantEvaluator=true -DskipVm=true`
has erroneous misses, for instance (but not limited to) asserts.
These are caused by errors in the VM.

A follow-up CL will be created to turn on "stressConstantEvaluator" by
default and print out any sucesses in the expect files.
