Avoid blocking the UI when searching for animation channels with Ctrl+F. Instead of showing a single text input in a blocking popup, Ctrl+F now just focuses the search box above the channel list. It feels nicer to use and has the niceties that come from using that textbox, like searching per keystroke, compared to the old pop-up method. As the behaviour of the operator has changed considerably, this also changes the operator name from `anim.channels_find` to `anim.channels_select_filter` and updates the keymaps.
