39a72be5 - [Clang] [NFC] Introduce `ConstDynamicRecursiveASTVisitor` (reland) (#124821)

[Clang] [NFC] Introduce `ConstDynamicRecursiveASTVisitor` (reland) (#124821) This relands #122991 (eeefa72). The last attempt at landing this caused some problems; I’m not entirely sure what happened, but it might have been due to an unnecessary use of the `template` keyword in a few places. This removes that and attempts to land the change again.
