Summary: Tidy check behavior often depends on language and/or clang-tidy options. This revision allows a user of TranformerClangTidyCheck to pass rule _generator_ in place of a rule, where the generator takes both the language and clang-tidy options. Additionally, the generator returns an `Optional` to allow for the case where the check is deemed irrelevant/disable based on those options.

Summary:
In general, the `Explanation` field is optional in `RewriteRule` cases. But,
because the primary purpose of clang-tidy checks is to provide users with
diagnostics, we assume that a missing explanation is a bug. This change adds an
assertion that checks all cases for an explanation, and updates the code to rely
on that assertion correspondingly.

This revision introduces an adaptor from Transformer's rewrite rules
(`clang::tooling::RewriteRule`) to `ClangTidyCheck`. For example, given a
RewriteRule `MyCheckAsRewriteRule`, it lets one define a tidy check as follows:
```
class MyTidyCheck : public TransformerClangTidyCheck {
public:
MyTidyCheck(StringRef Name, ClangTidyContext *Context)
: TransformerClangTidyCheck(MyCheckAsRewriteRule, Name, Context) {}
};
```
