docs: move asm-annotations.rst into core-api

This one file should not really be in the top-level documentation
directory.  core-api/ may not be a perfect fit but seems to be best, so
move it there.  Adjust a couple of internal document references to make
them location-independent, and point checkpatch.pl at the new location.
