Add string conversion for InstructionControlFlowKind enum

Refactor the string conversion of the `lldb::InstructionControlFlowKind` enum out
of `Instruction::Dump` to enable reuse of this logic by the
JSON TraceDumper (to be implemented in separate diff).

Will coordinate the landing of this change with D130320 since there will be a minor merge conflict between
these changes.

Test Plan:
Run unittests
```
> ninja check-lldb
[4/5] Running lldb unit test suite

Testing Time: 10.13s
  Passed: 1084
```

Verify '-k' flag's output
```
