Implementing CPropertyPoolHandler and CPropertyPool in HLSL, using direct buffer address instead of allocating descriptors sets for buffers.
Notes about impl:
-> Currently uses descritor pools (needs to allocate every time)
-> Use BDA and root constants with the addresses instead
-> Device capabilities traits
-> Example version: https://github.com/Devsh-Graphics-Programming/Nabla/blob/vulkan_1_3/include/nbl/builtin/hlsl/device_capabilities_traits.hlsl
-> maxOptimallyResidentWorkgroupInvocations
-> Can use nbl::hlsl::jit::device_capabilities struct with JIT generated "constexpr" variables for maximally optimal workgroup invocations

=== tasks ===
-> Port https://github.com/Devsh-Graphics-Programming/Nabla/blob/master/include/nbl/builtin/glsl/property_pool/copy.comp to HLSL
-> Persitently resident threads, scrolling over, maximally using the GPU workgroup size
-> Dispatch: 2D (x: DWORD in the property ID, y: property ID)
-> property id: which buffer youre touching/analogous to draw id
-> indexes into transferData
-> new version: use null pointer as invalid pointer
-> transferData: List of copy "commands"
-> new version: Replaced by push constant with BDA address
-> addresses: "Index buffer"
-> invalid pointer: IOTA (analogous to not using an index buffer, use iteration index as the fetching index)
-> Use shorts (uint16) instead of DWORDs (uint32)
-> Transfer data struct uses bytes for future proofing
-> Specialize on:
-> Whether or not source is a fill
-> Type of index (uint8, uint16, uint32, uint64)
-> Src index is IOTA
-> Dst index is IOTA
-> Keep optimization for modulos (line 38 & 52)
-> CPU Code
-> CPropertyPoolHandler
-> Nuke m_maxPropertiesPerPass, getMaxScratchSize (not relevant with BDA version)
-> TransferRequest on CPU keeps reference to the buffer and places it in the command buffer for lifetime tracking
-> Have a custom command that just keeps track of a **variable number** of reference counted objects for preserving lifetimes (LinkedPreservedLifetimes?)
-> Take a span of IGPUReferenceCounted
-> Example: https://github.com/Devsh-Graphics-Programming/Nabla/blob/master/src/nbl/video/IGPUCommandBuffer.cpp#L104C54-L104C54
-> For variable amount of stuff: https://github.com/Devsh-Graphics-Programming/Nabla/blob/master/src/nbl/video/IGPUCommandBuffer.cpp#L403C90-L403C90
-> Signature example: `IGPUCommandBuffer::preserveLifetime(std::span<const core::IReferenceCounted>)`
-> New transfer property signature
-> make pipeline barriers more robust (or require everything to be done properly outside the function)
-> First parameter: SIntendedSubmitInfo (IUtilities-independent submit info struct thing for handling overflows)
-> Source for it: https://github.com/Devsh-Graphics-Programming/Nabla/blob/vulkan_1_3/include/nbl/video/utilities/SIntendedSubmitInfo.h
-> Move IUtilities::autoSubmit and IUtilities::autoSubmitAndBlock to SIntendedSubmitInfo as static method (no more relation to IUtilities)
-> Second parameter: struct with parameters
`const asset::SBufferBinding<video::IGPUBuffer>& scratch, system::logger_opt_ptr logger, const size_t baseDWORD=0ull, const size_t endDWORD=~0u`
-> Additional parameters that are optional including additional pipeline barrier values
bitfield/boolean [pre|post]ScratchBarrier = true
-> lets keep MaxPropertiesPerDispatch and have it equal to 64kb/sizeof(nbl::hlsl::property_pools::transferTrequest)
-> instead of copy lambda logic at https://github.com/Devsh-Graphics-Programming/Nabla/blob/master/src/nbl/video/utilities/CPropertyPoolHandler.cpp#L172, fail if over MaxPropertiesPerDispatch
-> leave upstreaming thing & contiguous buffers for later (#ifdef 0 it out)
-> transferProperties with upstreaming & freeProperties
-> IPropertyPool
-> allocateProperties: use span instead of begin & end
-> (behaviour)
-> goes through indices to find empty ones and allocate them
-> if it's contiguous: add mapping from index to addr and addr to index
-> nuke descriptor set stuff (line 198 -> 211)
-> validateBlocks: change offset check (https://github.com/Devsh-Graphics-Programming/Nabla/blob/64cbb652e39acf0239a61bcee7fc26d70ab8d089/src/nbl/video/utilities/IPropertyPool.cpp#L38) to BDA
-> check usages & non null address
-> CPropertyPool: don't change anything, just make sure identation is right
-> MegaDescriptorSet (Descriptor set sub-allocate)
-> Have a multi-timeline event functor with IFuture await
```cpp
MultiTimelineEventHandlerST<DeferredFreeFunctor> deferredFrees;
deferredFrees.latch(futureWait,std::move(functor));
-> Also have it on IPropertyPool
-> Solve synchronization issues
-> create example testing downloads, uploads of properties
-> with IB, without IB, fills, etc etc
-> use regular buffer for everything
-> later test the streaming buffers (ifdef them back in)
