The great Skylark -> Starlark class migration:
  SkylarkRuleClassSerializer
  SkylarkProviderIdentifierCodecTest
  SkylarkProviderIdentifier

Rough algorithm:
 - Convert these class names
 - Convert methods, variables, other symbols encountered in the files these
 classes are defined in.
- *Don't* replace class names for classes defined in other files. These will
 be handled in their own order. This helps keep individual changelist scope
 small.
