Allow the screen capturer to capture oversized cursors and cursors without alpha channel (Windows).
    
Changes in this CL:
  - CaptureCursor() scans the cursor to verify that it has alpha channel.
  - The AND mask of the cursor is used to reconstruct transparency if the cursor does not have alpha channel.
  - CaptureCursor() always outlines the cursor when a "screen reverse" pixel detected.  Previously it was only done for black and while cursors.
    
Added desktop_capture_unittest.MouseCursorShapeTest to test the cursor conversion code.
