While working on #136907, I noticed issues with how we position and size
elements in the File/Asset Browser:
- A padding meant for outside the list "tiles" was applied inside, resulting
in unnecessary/unintended extra space between previews and their label, and
too small vertical paddings between tiles (see screenshots in PR).
- The height of text was measured based on the font size (not the actual line
height) and scaled up by some arbitrary amount. Made it hard to draw
multi-line text well, as done in #136907.
- Icons in list views were not centered vertically.
- The vertical list offset the entire list by the padding meant for tiles. Not
quite sure if intentional, I think it looks better with it. But code was
confusing since suddenly this extra tile padding was thrown in. Should be a
separate padding.
All these changes are a bit intertwined, so submitting them together.
Basically this makes paddings be applied more consistently and fixes related
issues, so the code makes much more sense.
