mesa: add new gl_driver_flags::NewWindowRectangles

This new driver flag will replace _NEW_SCISSOR which is
emitted when setting new window rectangles but it actually
triggers useless changes in the state tracker (like scissor
and rasterizer).

EXT_window_rectangles is currently only supported by Nouveau.
