intel: Add HiZ operations to intel_context::vtbl for all drivers

Add the following to the vtbl:
    hiz_resolve_depthbuffer
    hiz_resolve_hizbuffer

For all drivers for which HiZ is not enabled, the methods are set to be
no-ops. If HiZ is enabled, the methods are currently to set to empty
stubs.
