[MPS] Fix binary ops between int32 tensor with int64 scalar (#80220)
For some reason, tensor *op* scalar does not follow the normal binary promotion rules
So cast output tensor to expected type if needed
It seems that one should have casted input tensors to expected output tensor type, but it does not really work for boolean binary ops, so...
Add output tensor type/shape to cached graph key
Extend `TestMPS. test_add_scalars` to test for this regression
Fixes #79835
