fb: cfb_shell: Add draw text command

Browse Source 
Add the `draw text` command to execute the `cfb_draw_text()` API.

The command is similar to the `print` command. The difference is
`draw text` can render to coordinate that is not on tile boundaries.
The command is not run `cfb_framebuffer_clear()`,
So it allows rendering appendiceal with keeping already drawn image.
