[NFC] [Sema] [Modules] Use DynamicRecursiveASTVisitor to reduce generted code size (llvm#151074)

It is better to use DynamicRecursiveASTVisitor than RecursiveASTVisitor
as it can reduce the generated size. And also avoid using a template
type to present callbacks to avoid generating more code too.
