intel: move alloc functions to util

To support global extensions, needed to add pointer
to the intel_instance structure in the intel_handle.
That broke things that were using the icd pointer in the
handle and to avoid catch-22 between the intel.h and instance.h
needed to separate the alloc routines to their own file
rather than static inline in intel.h.
