debugger: Add refinements to the UI (#35940)

Took a little bit of time to add just a handful of small tweaks to the
debugger UI so it looks slightly more polished. This PR includes
adjustments to size, focus styles, and more in icon buttons, overall
spacing nudges in each section pane, making tooltip labels title case
(for overall consistency), and some icon SVG iteration.
