debugger: Open debugger panel on session startup (#29186)

Now all debug sessions are routed through the debug panel and are
started synchronously instead of by a task that returns a session once
the initialization process is finished. A session is `Mode::Booting`
while it's starting the debug adapter process and then transitions to
`Mode::Running` once this is completed.

This PR also added new tests for the dap logger, reverse start debugging
request, and debugging over SSH.

Release Notes:

- N/A
