New Binding 3
Initial size is UINT32_MAX
Updated to be sized DESC_ARRAY3_SIZE
Used in the shader to ensure the binding is referenced
Stress tests the FetchShaderFeedback code when it computes the maximum size of feedbackStorageSize.
* There's not a good accepted terminology for this kind of event, and for
historical reasons 'drawcall' has been the accepted term, even though
that can be quite confusing when a dispatch or a copy is a 'drawcall'.
* This is particularly highlighted by the event browser filters where
$draw() includes draws and dispatches, but $dispatch() only includes
dispatches, it's hard to intuitively understand why $draw() matches all
of these calls.
* As a result we've defined the term 'action' to cover these types of
events in the same way that we defined 'event' in the first place to
mean a single atomic API call.
* Even if a function isn't passed a global binding array as a parameter, we
still need to patch it in order to find any accesses it makes directly to
global resources just as we do in the entry point.
* This is better than testing by platform/platform version, because we can check
specifically for extensions and avoid running a test we know will fail because
extensions aren't supported.
* This is a simple test using descriptor indexing in fragment and compute
shaders, with sampled images and storage buffers, including passing bindless
arrays through functions to be sure that's tracked properly.
* There's also a define to turn on a reasonably bad case (though not
worst/extreme) of # of descriptors - roughly 5 million descriptors allocated
in total, with roughly 1 million bound at draw time.
