This extension is controlled by the ESSL feature level. Bump it up since
all parts of OES_gpu_shader5 should be supported.
This also avoids lowering all of the "advanced" functions (which should
probably not be lowered in the first place since they're part of ES
3.1...)

Widens the given bit mask by a multiplier, meaning that it will
replicate each bit by that amount.
For example: 0b101 widened by 2 will become: 0b110011
This is typically used in shader I/O to transform a 64-bit
writemask to a 32-bit writemask.
Moving this function here because it is used in multiple places.

Even for drivers not supporting layers, we need to include the layer
coordinate (zero in this case) when using array textures in the
download/upload FS.
Otherwise we are missing a component to get the texture, which ends up
in a malformed NIR shader.

- Do not emit needless layer code.

In the V3D driver there is a NIR lowering step for `image_store`
intrinsic, where the image store format is required for doing the proper
lowering.
Thus, let's define it for the download FS instead of
keeping it as NONE.
v2 (Illia)
- Use format only for drivers not supporting format-less writing.
v4 (Illia):
- Use PIPE_CAP_IMAGE_STORE_FORMATTED to reduce combinations.
v5 (Ilia):
- Use indirect array for download FS in not formatless-store support
drivers.

If PBO require to use a GS, this is created with TGSI.
For drivers preferring NIR shaders, they need to translate it from TGSI
to NIR. But unfortunately TGSI to NIR for GS is not implemented, which

So far we were relying on the supported formats filtering when
creating images from the user API.
But for some other (internal) uses, some of the formats that pass the
filter need to be restricted when binding them as shader images, as they
are not supported for this case.

From the GL_OES_texture_buffer spec:
"If no buffer object is bound to the buffer texture, the results
of the texel access are undefined."
this can be interpreted as allowing any result to come back, but not
terminate the program.
The current solution is not entirely complete, as it could still try to
get a wrong address for the shader state address.
This can be checked with piglit test
arb_texture_buffer_object-render-no-bo; the test is skip because it
requires OpenGL 3.1, but if overriding the version then it will crash.

Engines based contexts operate somewhat different for executing
batches. Previously, we would specify a bitmask value such as
I915_EXEC_RENDER to specify to run the batch on the render ring.
With engines contexts, instead this becomes an array of "engines", and
when the context is created we specify the class and instance of the
engine.
Each index in the array has a separate hardware-context. Previously we
had to create separate kernel level contexts to create multiple
hardware contexts, but now a single kernel context can own multiple
hardware contexts.
Another forward looking advantage to using the engines based contexts
is that the kernel does not plan to add new supported I915_EXEC_FOO
masks, whereas they instead plan to add new I915_ENGINE_CLASS_FOO
engine classes. Therefore some rings may only be usable with an engine
based class.
