[Payment Request][Desktop] Add dark mode Chrome logo.

Before this patch, Chrome in dark mode (on desktop) would display light
gray "chrome" text on dark gray background in the payment sheet. The
text was not readable.

This patch adds the white text logo and uses it when the dark mode is
enabled.

After this patch, Chrome in dark mode displays white "chrome" text on
dark gray background. This is readable.
