UI: New option to invert search filter in Dopesheet

A lot of animator request an option to invert the filter of the dopesheet channels. This patch adds that invert filter option. This is not for Grease Pencil only, affect to all modes.

Note: I have seen the new button has a rounded borders on the left. It would be better get rectangle shape, but not sure how to do it.
