Splits the `ErrorClassInfo` class into two classes:
- `ErrorClassInfo`, representing any concrete error class in the
analyzer or linter.
- `GeneratedErrorClassInfo`, representing an error class that is code
generated.
Also, adds `linterLintCodeInfo` to the `errorClasses` list. This list
now describes all concrete error error classes in the analyzer and
linter, whether they are generated or not.
This paves the way for a follow-up CL which will use the
`errorClasses` list to validate that any analyzer error codes
referenced by a `messages.yaml` entry (such as those in
`pkg/_fe_analyzer_shared/messages.yaml` or
`pkg/front_end/messages.yaml` refer to existing error classes.
