UX: header search mobile support - follow up (#32306)

### Changes made

#### Styling
1. added `4px` spacing between search input and cancel button
2. increased cancel button size (with padding) to match input height
3. decreased search panel padding by 1/2 from 16px to 8px
4. animation show/hide changed (from vertical to horizontal) and made it
quicker (300ms->200ms)
5. set html unscrollable when search panel is open

#### Dev
1. changed `data-test-` value to be consistent with other element's
attrs values
2. clear search action tag changed from `<a>` to `<DButton>`
