Add keyboard support for filter bar

[dhruvisompura]

Addresses #8529

This PR adds the missing Enter/Space keyboard support for our filter search bars. This change effects the summary panel search bar and the variables pane search bar.

I also removed a couple duplicate search/filter components that are not being used.

Thanks for fixing so fast! Quick question, when the "x" is selected and the user hits Enter to clear the search data, where should the focus go next? I assumed it would be in the search input (it's currently not)... but I'm not sure.

It should be in the search input! I'll take a look into this. Thanks for catching that!

(Sorry I thought I had reviewed this a while back!)

Looks good to me. I always like a good PR with a 17 times more deleted code than added.
