Update icons to use tint and vectors

A bunch of icons were using PNGs which didn't allow their color
to change when in dark mode. This CL simply adds vector drawables
for all the PNGs and sets the tint to the correct color where needed.

Test: visual inspection, robotests pass
Bug: 126199274
Change-Id: I372d94e374173ab0572dacb03674a40fa14cffb9
