anv_format::surface_format was incorrect for Vulkan depth formats.
For example, the format table mapped
VK_FORMAT_D24_UNORM -> .surface_format = D24_UNORM_X8_UINT
VK_FORMAT_D32_FLOAT -> .surface_format = D32_FLOAT
but should have mapped
VK_FORMAT_D24_UNORM -> .surface_format = R24_UNORM_X8_TYPELESS
VK_FORMAT_D32_FLOAT -> .surface_format = R32_FLOAT
The Crucible test func.depthstencil.basic passed despite the bug, but
only because it did not attempt to texture from the depth surface.
The core problem is that RENDER_SURFACE_STATE.SurfaceFormat and
3DSTATE_DEPTH_BUFFER.SurfaceFormat are distinct types. Considering them
as enum spaces, the two enum spaces have incompatible collisions.
Fix this by adding a new field 'depth_format' to struct anv_format.
Refer to brw_surface_formats.c:translate_tex_format() for precedent.
I misinterpreted anv_format::format as a VkFormat. Instead, it is
a hardware surface format (RENDER_SURFACE_STATE.SurfaceFormat). Rename
the field to 'surface_format' to make it unambiguous.
The brw_create_nir function takes a GLSL or ARB shader and turns it into a
NIR shader. The guts of the optimization and lowering code is now split
into a new brw_process_shader function.
As of this commit, nothing actually needs the brw_context.

This way we can stop doing is_gles3 checks inside of the compiler.

Previously, these were pulled out of the GL context conditionally based on
whether we were running ff/ARB or a GLSL program. Now, we just pass them
in so that the visitor doesn't have to grab them itself.

Previously, each shader took 3 shader time indices which were potentially
at arbirary points in the shader time buffer. Now, each shader gets a
single index which refers to 3 consecutive locations in the buffer. This
simplifies some of the logic at the cost of having a magic 3 a few places.

This creates the options at screen cration time and then we just copy them
into the context at context creation time. We also move is_scalar to the
brw_compiler structure.
We also end up manually setting some values that the core would have set by
default for us. Fortunately, there are only two non-zero shader compiler
option defaults that we aren't overriding anyway so this isn't a big deal.
