[lldb-mi] Fix implementation for a few mi commands

Summary:
Some of the mi commands implemented in lldb-mi are incomplete/not confirming to the spec.
- `gdb-show` and `gdb-set` doesn't support getting/setting `disassembly-flavor`
- `environment-cd` should also change the working directory for inferior
- debugger CLI output should be printed as console-stream-output record, rather than being dumped directly
to stdout
- `target-select` should provide inner error message in mi response
