Don't pre-scale vector drawables in settings

The idea of scaling down icons to prevent the system from
dealing with large images seems to be catching some
VectorDrawables and rescaling them. I don't think
VectorDrawables are likely to create a memory issue,
and the protection code seemed to be added to protect
against large pngs, not vector graphics.

Bug: 70562945
Test: Visually verified that all icons in the Accessibility
Shortcut list are now the same size with maximum display
and font sizes.
