clean-up: Remove uselsess mentions of CONFIG_COMMAND_HISTORY

These were reminders that somehow slipped through the cracks
or were erroneously introduced after previous clean-ups.

Getting rid of then once again. Hopefully for good now :)

Where missing and appropriate replace with CONFIG_CMDLINE_EDITING
which really enables shell history as of now.
