Vulkan doesn't have a conversion from uint32_t/int32_t to float. It does have conversions from 16/8 bits. Main reason is that Vulkan expects that there is no benefit when converting 32 bits from one type to the other and should be solved by passing the right data type. In Blender however this isn't the case as there are benefits on other GPU backends (OpenGL for example). This PR adds helper function to check if conversion is needed and perform any conversions in place. It also implements the function to upload vertex buffers to the GPU. NOTE: Test cases have been added to validate this, but they are not able to run on the Vulkan backend just yet, because they require the graphics pipeline to be available.
