panvk: Advertise VK_KHR_shader_untyped_pointers on v9+

Browse source 
Enable the VK_KHR_shader_untyped_pointers extension and the
shaderUntypedPointers feature for Valhall and newer (v9+).

Bifrost (v6/v7) has issues with 8-bit vector loads through untyped
pointers combined with 16-bit storage, so restrict the extension
to architectures where it's fully functional.
