lima: support rectangle texture

Browse source 
As Vasily discovered, the bit 7 of the word 1 of the texture descriptor
is set when reloading the framebuffer, to use framebuffer-based offset
rather than normalized one. This bit also works for regular textures to
enable accessing with non-normalized offset.

Add support for rectangle texture by setting this bit for
PIPE_TEXTURE_RECT.
