Light-weight detection of static content when using WGC

This CL adds a light-weight detection of "frame content has changed
since last frame" to an existing pass where bytes are copied from a
texture to a DesktopFrame. The resulting boolean can then later be
used to bypass a full detection of if the content is static or not.
As a result, we only check for static content for a small fraction of
all captured WGC frames and this reduces the total load when 0Hz
is enabled for WGC.

Both WGC and 0Hz support for WGC is still behind a flag.
