Initial support for immediate mode emulation in Vulkan.
This implementation doesn't cache and is expected to
be slow.

Most work was spent on making VKVertexAttributreObject
usable for both Batches and Immediate mode (#106224)

b0563f520e Added test for offscreen rendering. 
It doesn't validate anything yet, it should (for now) be used
with renderdoc.
29cc37cf22 GPU: Add texture usage parameter to GPUOffscreen. 
Currently the Textures used for offscreen rendering don't have
the `GPU_TEXTURE_USAGE_HOST_READ` flag. But some cases it is
needed. This PR adds a parameter when creating an offscreen
buffer.

Other solution could be to add this flag to all textures, but
we chose not to do this as that reduces the amount of fine-tuning
options for Metal/Vulkan backends. GPU can store textures
differently based on its actual usage.

This option isn't available in the python API as we don't expect
add-on developers to fine-tune texture usages to this extent.
