fix: impose a memory limit

[onbjerg]

Some Foundry tests might access memory at very high indexes that would not otherwise be possible due to gas constraints. A solution would be to lower the amount of gas tests can use, but ideally we'd want this to be as uncapped as possible to allow for deployment of big test contracts.

This imposes a memory limit of 16 megabytes for the interpreter which (I think?) should be more than enough. Let me know what you think/if there is a better solution. Could also be feature-gated

I feal like this is not the best way to do it, i still need to check how geth and oe bahave in this case just to be on same page with them.

Wouldn't this fit better in OverrideSpec? Idk if Foundry uses an Inspector though, which is needed to use OverrideSpec, but I guess it does.

Dragan previously talked about removing the override spec thing so I opted not to put it in there. Foundry doesn't use it either 😄

@rakita This is now hidden behind the memory_limit feature and is configurable through CfgEnv. Let me know your thoughts.

I also removed interpreter.call_depth since you can just use subroutine.depth() instead
