GBE/Runtime: Optimize Sample/TypedWrite instruction.

GBE/Runtime: Optimize Sample/TypedWrite instruction.

This commit does two major things as below:
1. Allocate image surface at compile time, and add new gbe interfaces to let runtime know
how many image surfaces we have, and the image allocation informations. Thus the runtime
library know how to bind those image surfaces.

2. As now for both image and sampler, at compile time, we know the eaxct binding table
index. We no longer need to get those index from the input argument(curbe) and prepare
the desc to the architecture register. We can use imm as the desc thus we can save
4 out of 4 instructions for SampleInstruction and save 2 out of 12 instructions for
the TypedWriteInstruction.

This patch is also a major prepartion for the get_image_width/height/... functions.
