ir3,tu: include ir3 debug flags in shader hash key

Many debug flags influence shader codegen but are currently not included
in the hash key. This causes surprising effects as cache lookups may
return shaders compiled with different debug flags than currently in
effect. This patch fixes this by including all debug flags  in the
shader hash key.
