This change disables native cursor capture in WgcCapturerWin to better
support the existing idiom of wrapping a capturer in a
DesktopAndCursorComposer. That means we also need to set the top_left
property of output DesktopFrames, so I've also implemented GetTopLeft in
WgcCaptureSource to facilitate this. I've also added a few unit tests
for WgcCaptureSource.

This changes modifies EnumerateCapturableWindows to accept an optional
parameter consisting of extended window styles that will prevent windows
with the specified styles from being returned. This allows us to filter
out windows with the WS_EX_TOOLWINDOW style for the WgcCapturerWin,
which does not support capture of such windows.

WgcCaptureSession would crash when copying the frame data for an image
from a portrait oriented monitor. This is because we were using the
height of the image multiplied by the rowpitch of the buffer to
determine the size of the data to be copied. However, in portrait
mode the height measures the same dimension as the rowpitch, leading
to us overrunning the frame buffer.
The fix is to use the height and width of the image multiplied by
the number of bytes per pixel to determine how much data to copy
out of the buffer, and only use the rowpitch to advance the pointer
in the source data buffer. This has the added benefit of giving us
contiguous data, reducing the size of the DesktopFrame that we output.
