Respect kRectsMustMatchForMSAASrc_BlitFramebufferFlag in dst setup
Crurently, when preparing a texture for blitFramebuffer, we ignore the
kRectsMustMatchForMSAASrc_BlitFramebufferFlag, and may attempt to
copy from one src rect to a different dst rect.
This change updates initDescForDstCopy and setupDstTexture to allocate
larger textures if necessary and accomodate this flags requirements.
