Consider removing CORINFO_HELP_CHKCASTARRAY and CORINFO_HELP_ISINSTANCEOFARRAY from JIT/EE interface #91016
Description
An attempt was made in #89548, but it turned out to be trickier than expected.
While these helpers are not used at run time (they are mapped to "ANY" variants), there is dependency at JIT time as JIT considers these helpers when making optimization choices.
It is possible that a different API would be more appropriate or less fragile here.
