[analyzer][NFC] Supply CheckerRegistry with AnalyzerOptions

[Szelethus]

Summary

Since pretty much all methods of CheckerRegistry has AnalyzerOptions as an argument, it makes sense to just simply require it in it's constructor.

[NoQ]

Yup, totally.

 /// For example, the checker "core.builtin.NoReturnFunctionChecker" will be
 /// included if initializeManager() is called with an option of "core",
 /// "core.builtin", or the full name "core.builtin.NoReturnFunctionChecker".
