SearchKit - Add sticky table header style

[colemanw]

Overview

Allows SearchKit table displays to have "sticky" headers which don't scroll past the top of the screen.

Technical Details

The tricky part was figuring out the exact location to "stick" to. The position of the bottom of the menubar is different depending on the CMS, the menubar settings, the screen width, the number of items in the menu, etc. CSS variables to the rescue!

r-run: ok - works as expected on D7 with and without the drupal menu exposed.

I like the new class - much better than the css hack as you can choose per table whether to use sticky headers.

Thanks @aydun FYI I've also run it in Wordpress with various permutations of screen width and menubar settings.
