[Chipbar] Update to material colors.

Note: I removed the common <color> reference because it can't reference
attributes. I added a lint IfChange/ThenChange, which isn't supported by
our linters (yet?) but will at least point people to the other file that
needs to be modified.

Fixes: 267821684
Test: media push to receiver flow w/ app icon (light & dark theme)
Test: media pull to phone flow w/ generic icon (light & dark theme)
Test: active unlock flow (light & dark theme)
