[Impeller] Avoid loading redundant Vulkan extensions. (#51818)

All dependencies of VK_ANDROID_external_memory_android_hardware_buffer were enabled earlier. But I didn't realize that those extensions became core in Vulkan 1.1. There is no need to load them unnecessarily. It just makes the extensions requirements look more complicated than they are.

Just deletes code. No change in functionality.
