[lworld] RFR: 8378247: [lworld] Move ciKlass::can_be_inline_klass to ciType

[Tobias Hartmann]

Moving `ciKlass::can_be_inline_klass` to `ciType` will simplify code and also avoid static analysis to complain about that `obj_type` in `GraphBuilder::monitorenter` could not be a `ciKlass` (which I think is a false positive, but hard to prove).

Thanks,
Tobias
