cc: Make RenderPassAndMaskWithPartialQuad not use arbitrary uvs

This is the only test that uses the available functionality of
RenderPassDrawQuad to specify an arbitrary uv rect.  All other users in
cc assume that the rect for the RenderPassDrawQuad also specifies the
uvs (with the origin being the start of the mask), modulo some scale if
the render pass is clipped.

This test conversion is just a refactoring step to make removing the uv
rect easier.

PTAL

This test now locates the mask at the origin, instead of at 50, 50.  But,
because the quad only starts at 50, 50, you only see the bottom right quadrant
of it.

cc/output/renderer_pixeltest.cc:1226: gfx::Rect sub_rect = gfx::Rect(50, 50,
200, 100);
Why not test more things while I'm here, like different mask and quad sizes...

can you name the image like "mask_bottom_right" or somethin?
