Fix popup window title color always being black with custom titlebar.

This patch changes the window title color when the titlebar is painted.
This ensures that the proper contrasting color is picked for both active
and inactive states. The color is also made partially transparent when
the window is inactive.

The end result is that the window title should always be the same color
as the window caption button symbols (unless a theme uses a button
background with the opposite luma of the titlebar).

Able to reproduce this issue on build without fix. Hence verifying the fix on latest canary 67.0.3383.0 using windows 10.

Observing faded font color when popup dialog is not active. Attaching screenshots for reference.

As fix is working as expected, adding Verified labels.

Thanks!
