Since we're using texelFetch with a sampled image, a sampler is no
longer needed. This agrees with the Vulkan Spec section 13.2.4
Descriptor Set Updates:
sampler is a sampler handle, and is used in descriptor updates for types
VK_DESCRIPTOR_TYPE_SAMPLER and VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER
if the binding being updated does not use immutable samplers.

The texelFetch operation requires that the sampled texture coordinates
be unnormalized integers. This will simplify the copy shader for
w-tiled images (stencil buffers).
v2 (Jason):
Use f2i for texel coords
Fix num_components indirectly
Use float inputs for interpolation
Nest tex_pos functions

The new organization is as follows:
* anv_meta_blit.c: Blit and state setup/teardown commands
* anv_meta_copy.c: Copy and update commands
* anv_meta_blit2d.c: 2D Blitter API commands
Also, change the formatting to contain most lines
within 80 columns.
