mesa: Refactor bounding-box calculation out of _mesa_update_draw_buffer_bounds

Drivers that currently use _Xmin and friends to set their scissor
rectangle will need to use this code directly once they are updated for
GL_ARB_viewport_array.

v2: Use different bit-test idiom and fix mixed tabs and spaces.  Both
were suggested by Ken.
