vulkan_device: Fully disable dynamic state extensions/features when dyna_state = 0

If the user selects dynamic state = 0, force-disable all Vulkan dynamic state extensions and related struct fields.
This ensures compatibility with drivers and simplifies shader pipeline logic.

Also logs all removals for clarity.
