Make TypeNameRule conform to ConfigurableRule

[jpsim]

All its options are currently hardcoded: https://github.com/realm/SwiftLint/blob/9d138ad691f55fd016f883eb4044649b150582b7/Source/SwiftLintFramework/Rules/TypeNameRule.swift

I can tackle this if you tell me what you'd like to make configurable. A cursory glance makes the min and max length stand out. There's a part of me that almost feels this should be broken into a length rule and a case rule. Actually 2 length rules if we want to follow the pattern from variable name length rules.

Actually 2 length rules if we want to follow the pattern from variable name length rules.

This was done before your dictionary-based configuration efforts. It would make much more sense IMO to have a type_name_length rule be configurable on both min_length and max_length.

That makes sense and would be more performant.

I can see a good way to accomplish this (as well as do a conversion for the variable rules). It would involve continuing the work of providing standardization on top of ConfigurableRule. I foresee the creation of standard configuration structs in this process. This would ultimately supersede the work done with ViolationLevelRule.
