Subject: [PATCH] Use CSS color-scheme instead of invert (#21616) (#21623)

Backport #21616 to 1.18

The
[`color-scheme`](https://developer.mozilla.org/en-US/docs/Web/CSS/color-scheme)
property changes the base color of certain form elements like the
datepicker icon in Chrome. Set it and remove the previous invert hack.

Before with invert removed:
