[Web Payment] Enable secure payment confirmation on Windows.

Before this patch, secure payment confirmation was available only on Mac
as an origin trial.

This patch enables the renderer origin trial on Windows and enables by
default the browser feature on Windows, too.

After this patch, websites that are running the secure payment
confirmation origin trial can enroll and exercise payment credentials on
Windows with Windows Hello in addition to the existing support for
TouchID on MacOS.

The current origin trial runs to M-89, so enabling the origin trial on
Windows in M-90 will have no effect until a new origin trial is started.

Intent to experiment on MacOS until M-89:
