hal/vulkan: Fix multi draw indirect emulating and respect maxDrawIndirectCount

[beicause]

Description
Noted this when I was checking #8162

The offset argument of draw_indexed_indirect in hal/vulkan seems incorrect. It should + i * stride.
Also multi draw indirect should respect limits.maxDrawIndirectCount.

Actually, vkCmdDrawIndirectCount vkCmdDrawIndexedIndirectCount vkCmdDrawMeshTasksIndirectCountEXT also require that the count in the countBuffer must be <= maxDrawIndirectCount, altough on many devices it's u32::MAX(vulkan gpuinfo)

Testing
I assume the code is correct, I don't have a device to test this.
