fix: add eyedropper tool functionality to browser view

[mlaurencin]

Description of Change

Closes #26883

This PR adds the functionality of the Chromium eyedropper when using the color picker tool. Previously when you clicked on the eyedropper from the color picker nothing would happen. The eyedropper now works as expected, as colors in the window can be selected.

There is a known issue (reported here) in Chromium where, in a multiple monitor setup, the tool may function incorrectly if the main monitor is not positioned in the upper left corner.

Fiddle: https://gist.github.com/mlaurencin/cb0f0b2d6b075e67721c41474c0f17da

Examples:

(Be aware that the color palette is not rendered in the screen capture, but was displayed like in the above image)
