* This is a test of a specific case of lazy serialisation, but in particular
D3D12 descriptors do some aliasing tricks for types to compress the data, so
repeated serialisation needs to be safe.
* Most of the main entry points that can fail with relevant reasons now has a
way of specifying a message to return with it. This message can be displayed
to the user to give more information or context about an error.

Fix a typo in a comment in D3D12_Descriptor_Indexing.py.
Fix UAV using a typed buffer view instead of a structured buffer view.
Fix SetDescriptorHeaps being called before ClearUnorderedAccessViewUint
* The pattern buffer is 64x8 but doing copies to each target location can cause
issues on very large textures. Instead we generate a 256x256 buffer with
repetitions on load (which is still only ~256-512kB), and copy from that. We
can still do truncated copies so we don't need a smaller buffer, and this
greatly reduces the number of buffer copies issued.
* This is a stupid requirement as the quad overdraw shader doesn't use any
interpolators, but the D3D12 runtime complains and refuses to create a PSO
unless the PS has a matching signature. This works as long as the position was
the first output from the previous stage, but if it isn't the PSO fails to
create.
* To fix this, we take the existing shader and patch it by grafting the output
signature from the last stage over onto the input signature, and patching up
where the position is.
* Normally we only check mapped memory when it's referenced during capture by
some binding, but for BDA we don't have bindings so we have to conservatively
check it every time.
