intel/blorp: Support blits and clears on surfaces with offsets

Browse Source 
For certain EGLImage cases, we represent a single slice or LOD of an
image with a byte offset to a tile and X/Y intratile offsets to the
given slice.  Most of i965 is fine with this but it breaks blorp.  This
is a terrible way to represent slices of a surface in EGL and we should
stop some day but that's a very scary and thorny path.  This gets blorp
to start working with those surfaces and fixes some dEQP EGL test bugs.
