* WebGPU: Add texture format (shaderc bin version 10)
* WebGPU: Simplify storage images + Fix format decorations
* Shaderc: Cleanup Texture name assumption in textures
* Swapchain class
* Headless support
* MSAA backbuffer
* Fix framebuffer resolve
layout transitions were missing and framebuffer mips and layers weren't used
* Fix blit with MSAA resolve source
only the main texture layout was transitioned
* Fix pipeline hash
* Vulkan: calculate vertex count from all streams, not just the first
...which might not exist in the first place
* Vulkan: use correct vertex stream offsets and handles
* D3D11: remember stream vertex count when no index buffer is bound
* Don't enable optional extensions if BGFX_CONFIG_RENDERER_USE_EXTENSIONS is 0
* Support rendering to slices of 3D textures
* Create transient command pool
* Blit array layers for non-cube textures
* Clean up destroy and release functions
Simplifies CommandQueueVK code, automatically sets handles to NULL after release(), removes the need for explicit StateCacheT instantiations, and enables usage of StateCacheLru
* Fix renderpass hash calculation
* Allow sampling cube array textures
* Make StateCacheLru work with types overloading the address-of operator
* Alias textures to shader sampler type
Requires shaders with shaderc binary version 8 or higher
* Fix 32-bit compilation
If you do
```
bgfx::setIndexBuffer()
bgfx::submit(BGFX_DISCARD_NONE)
bgfx::submit()
```
then the second submit will be broken because even though it still uses the correct index buffer it will lose the BGFX_SUBMIT_INTERNAL_INDEX32 state.
Basically all multi-pass calls involving a 32index buffer are broken currently in bgfx master.
This fixes bug introduced by 5c304dad3b
