Feature: Add the ability to copy the text from the OmniBar when searching

### What feature or improvement do you think would benefit Files?

When searching using the OmniBar, you cannot select or edit the text you searched for. When clicking or attempting to highlight text on the OmniBar, it instead shows "Home" or the location you started searching at.

^ If I click on the OmniBar to edit my search, it instead makes me edit the address bar. It would be nice to be able to edit my search instead of editing the text in the address bar.

### Requirements

- This will make it easier for users to edit their search, instead of cancelling, re-opening the OmniBar and rewriting everything.
- It also avoids confusion in the UI.
