Add Spike's meta files for pkg-config

This commit adds the *.pc files for Spike's simulation library,
enabling dynamic and static linking without the need to directly
reference Spike sources. Using Spike as a stand-alone library
provides an interesting option for developing tools
and applications based on Spike.
