Refine styles of controls to match Compound

This changes the styles of buttons, other form controls, and tabs in settings to:

1. Improve their usage of semantic colors, so that they adapt correctly to custom themes
2. Make them more visually coherent with the new Compound design system, as we integrate more of it into the app

This is a re-introduction of matrix-org#12241 with the difference that we're now using our branding colors again on form colors, and buttons have become rounded to match the appearance of new Compound buttons.
