commands: refactor registration

Register all commands with the same function and store them in the same
map.

Use bit flags to determine in which contexts each command should be
available.

Remove duplicate commands now that the same command can be exposed in
multiple contexts.

Refactor API to allow executing commands from other commands without
import cycles.
