Restore the blue highlight for GTK on Omnibox results.

The way GTK theming is plumbed through is very subtle, and we don't
know yet how that should influence new color schemes.

This CL tries to isolate (and make explicit) the complexity required
for GTK theming on Desktop Linux by introducing OmniboxTint::NATIVE,
as distinct from LIGHT and DARK used everywhere else.

Able to reproduce the issue on chrome build without fix
Verified the fix on Ubuntu 14.04 on Chrome version #67.0.3365.0 as per the comment#0
Attaching screen cast for reference.
Observed "able to see highlighted text in Omnibox search"
Hence, the fix is working as expected.
Adding the verified label.

Thanks!

Ensure omnibox_theme.cc adapts to theme changes.

This is easily done with an override of View::OnThemeChanged()

Less easily done is a test: themes are complex. Add a test for the
selection highlight, which captures the current logic around theme
color propagation.
