  Log Message:
  -----------
  [clang-tidy] Added support for validating configuration options

Summary:
Adds support for `ClangTidyCheck::OptionsView` to deteremine:
  - If an option is found in the configuration.
  - If an integer option read from configuration is parsable to an integer.
  - Parse and Serialize enum configuration options directly using a mapping from `llvm::StringRef` to `EnumType`.
  - If an integer or enum option isn't parseable but there is a default value it will issue a warning to stderr that the config value hasn't been used.
  - If an enum option isn't parsable it can provide a hint if the value was a typo.
