Use BCryptGenRandom when building as Windows UWP app.

RtlGenRandom is a legacy API that might be altered and is unavailable
for UWP apps. BCryptGenRandom is the recommended API for generating
random numbers on UWP.

This change causes BCryptGenRandom to be used for UWP apps and
RtlGenRandom to be used on non-UWP apps (i.e. desktop apps). For non-UWP
configurations, RtlGenRandom is used instead of BCryptGenRandom to avoid
accessing resources that may be unavailable inside the Chromium sandbox.
