marks applied in parametrize are stored as markdecorator

[RonnyPfannschmidt]

while parametrizing i found that things break appart due to the markers coming from the parameterization are stored as markdecorator instead of marks

this is also the final line for me wrt trying to keep marks backward compatible ^^

i plan to break them now in terms of internals to we can get something usable

this triggers #1540

this was in part resolved by introducing pytest.param

fixed in #3317
