Fixed parametrized markers over staticmethod and classmethod decorators.
closes #12863

An interesting thing about this solution and python (<3.9 vs 3.10<) compatibility:
In python3.10, they changed @staticmethod and @classmethod decorators to inherit method attributes.
Before that version, functions wrapped with them did not return true for callable() func, so it failed tests for py39 and succeeded for py310.

For example:

from pytest import mark

class TestA:
    @mark.parametrize("value", [1, 2])
    @staticmethod
    def test_foo(value: int):
        """Didn't work. Now fixed :)"""

    @pytest.mark.parametrize("value", [1, 2])
    @classmethod
    def test_bar(cls, value: int):
        """Didn't work. Now fixed :)"""

    @staticmethod
    @mark.parametrize("value", [1, 2])
    def test_baz(value: int):
        """Works"""
