bind_descriptors_batch()

void MayaFlux::Yantra::GpuResourceManager::bind_descriptors_batch	(	const std::string &	key,
		const std::vector< GpuBufferBinding > &	bindings
	)

Bind every non-image buffer binding in one Vulkan call.

Equivalent to calling bind_descriptor or bind_shared_descriptor once per non-image entry in bindings (routed the same way, by whether a shared slot exists at that (set, binding)), except every entry is submitted through a single vkUpdateDescriptorSets call. Image entries are skipped, matching bind_all_descriptors' existing split between buffer descriptors here and image descriptors bound separately per staged image.
