Split RecordKeeper `getAllDerivedDefinitions` family of functions into two variants: (a) non-const ones that return vectors of `Record *` and (b) const ones, that return vector/ArrayRef of `const Record *`. This will help gradual migration of TableGen backends to use `const RecordKeeper` and by implication change code to work with const pointers and better const correctness. Existing backends are not yet compatible with the const family of functions, so change them to use a non-constant `RecordKeeper` reference, till they are migrated.
