SWDEV-280473 - Support HSAIL shared library build

This change makes HSAIL usage similar to that of Comgr. By default, the
runtime will statically link against it, however if HSAIL_DYN_DLL is
defined, then the runtime will try to dynamically load HSAIL.

Currently stick to statically linking to HSAIL. In a feature patch the
dynamic loading behaviour will be enabled.
