vulkan: use pl_vk_inst_create

This change is mostly motivated by missing
VK_KHR_portability_enumeration instance extension when enumerating the
devices. Which causes issues with MoltenVK which does not advertise full
Vulkan conformance.

To avoid duplicating code use pl_vk_inst_create() which correctly query
availability and enables the mentioned extension.

While at it fix the VkInstance leaking in vk_validate_dev().
