fix(tests): un-skip remaining Amsterdam ported static tests and drop the skip list (Pt. 2d)

[spencer-tb]

Description

Final slice of the Part 2 ported static split (chain in #3264): the remaining un-skips — including the stCreate2 Berlin-twin consolidation into single parametrized tests and the revert_depth_create_address_collision restoration (the port never actually collided; the collider moved back onto the CREATE2 address, verified against the legacy filler). 19 files, the last 49 skip-list entries (49 → 0).

With the list empty, this deletes amsterdam_skip_list.txt and the conftest.py machinery that applied it, and lands the accumulated enhance-ported-test skill lessons.

Every touched test fills green across its full valid_from range, and the whole tests/ported_static/ tree fills green on Amsterdam with 0 skips. Stacked on Pt. 2c (#3321); the diff includes the earlier slices until they merge.

Follow-up to #3215.
