[turbofan] Drop obsolete unused JSStrictNotEqual operator.

[turbofan] Drop obsolete unused JSStrictNotEqual operator.

We don't need the JSStrictNotEqual operator in the compiler, because
this is never generated by the BytecodeGraphBuilder, and the code in
the AstGraphBuilder was dead code. Also remove the backing builtin
StrictNotEqual.
