this bumps the LVP_SHADER_STAGES to allow task/mesh shaders to be used,
and adds them to various state binding and execution places.

This is the big execution one, it implement the draw mesh callback.
This executes task shaders and mesh shaders with no overlap.
When task shaders finish, the mesh shader is launched using the payload
data, unless no task shader is run, then the mesh shader is launched.
Once the mesh shader is finished the data is supplied to the draw
pipeline to convert to linear vertex data with no per-prim data,
then passed to draw for clipping and further processing.

This allows generating task and mesh variants of compute shaders.
It adds:
- vertex and primitive outputs support - aos writing.
- payload support
- mesh iface for the output and count callbacks.
- draw_id
- multiple iteration support to the exec fn to allow launches
in multiple passes to reduce memory usage

This is just some infrastructure for creating shaders and contexts.
task/mesh shaders are based on compute shaders and share nearly all
their code with compute.

mesh shaders can have vertex and primitive outputs, and act a bit
like TCS shaders, add the callback to allow the driver to decide
how to store these.

mesh shading has a payload to pass between task and mesh shaders,
this acts like shared memory as well, so we use the standard memory
hooks to access it.
This current adds the payload after the 12-byte header which will
contain the x/y/z grid sizes.

This adds draw mesh shader infrastructure, as mesh shaders have
to be able to feed into the post vs stages like clipping, so
we have to wire informational things up.

This doesn't matter much in practice, because the integer an float
representations of zero are the same. But it's easier to understand
what's going on if the correct type is used, so let's clean this up.

It does not fix them. Now they just hit asserts in the compiler.

We need to tell the apps about the hardware limtations, so that they
have a chance to take a fallback path. Fixes GTK misrendering, due to
use of the dummy shaders (now properly fallbacks to software).
