Revert "gpui: Fix uniform list scrolling with vertical padding present" (#40891)

Finn Evers created 1 week ago

Reverts zed-industries/zed#40719

This unveiled some bigger issues with the UniformList size computations,
which are more crucial than what was fixed here.

Release Notes:

- NOTE: BUGFIX "Fixed a rare issue where the extension page would
stutter while scrolling." was reverted due to some other issues
