LOG: [CodeGen] Make TargetRegisterInfo destructor public (NFC) (#157341)

All in-tree targets store target-specific TRI in target-specific
Subtarget/InstrInfo class by value, but some downstream targets may
prefer to store it as `std::unique_ptr<const TargetRegisterInfo>` (to
avoid inclusion of MyTargetRegisterInfo.h in MySubtarget.h).

Making the destructor public makes this possible, and also follows
general C++ guidelines (the destructor should be either public virtual
or protected non-virtual).

All other related classes already have their destructors public.
