LOG: [NFC] Make unwind table internal data structures more accessible (#145804)

All these changes are being used in
[PR#145633](https://github.com/llvm/llvm-project/pull/145633)

`CFIProgram`:
- `addInstruction` methods already exists, but more convenient ones are
private, this PR makes them public

`UnwindLocation`:
- Added a field accessor method for `Dereference` like other field
access methods.

Added:
