Migrate code from stacks-core to clar2wasm

[krl]

This PR moves most code related to wasm to the clar2wasm repo.

It seems like where the code should be in the first place, and will make developing changes and tests much less painful.

Draft for now since i need to update the paths to use branches instead of hard-coded paths. This was done to make sure the stacks-core side is still working. A pr in that repo removing the code is coming as well soon.

From what I got, code that was on stacks-core was pushed to clarity-wasm repo and split into initialize, wasm_utils and linker files.

With that change, initialize is now the orchestrator when dealing with Clarity contracts initialization and execution on wasm.

All set os tests are running ok (only one regression already noted).

Code LGTM! Approved. But would be great to also have another pair of eyes on those changes. /cc @Acaccia

Good work @krl ! Thanks!
