[LTR] Implement Stone of Erech (#10497)

* [LTR] Implement Stone of Erech

Grouped together two other recent cards for that exact same replacement effect.

* refactor some more

This does extend the ReplacementEffect "If ... would die, exile it instead", using a `PermanentFilter`. [[Void Maw]] and [[Lorcan, Warlock Collector]] have thus be refactored to use that instead of a custom replacement effect.

Added a static filter `StaticFilters.FILTER_ANOTHER_CREATURE` for Void Maw that is filtering "another creature".
Found and refactored cards that were declaring that exact filter locally
* [[Flame-Kin War Scout]]
* [[Herd Gnarr]]
* [[Mogg Bombers]]
* [[Timid Drake]]

* fix void maw

* reverse changes on VoidMaw

Void Maw was a linked ability, so not exactly the same replacement effect that was refactored.
