This commit adds a set of commands to monitor for enabling breakpoint debugger.
This is implemented based on the walker utility for step-by-step LLB inspection.
For each vertex and breakpoint, monitor calls Solve API so the user can enter to
the debugger container on each vertex for inspection.
User can enter to the breakpoint debugger mode by --invoke=debug-step flag.

Print more understandable messages on error:
- When ps fails because the monitor doesn't attach to any session, print "no
attaching session" instead of "unknown ref".
- Avoid disconnect silently fails when the monitor doesn't attach to any
session. Print "no attaching session" error instead.
- Fix error message of "attach"'s arguments. ("server name must be passed" ->
"ID of session or process must be passed")

This commit moves monitor commands to `monior/commands` package.
Commands still need access to the `monitor` object and buildx controller so this
commit enables this via `Monitor` interface stored in `monitor/types`.
