Up until now, we cached export wrappers per export index. With the anyref proposal potentially many more functions will need export wrappers, e.g. any function that is stored in a table, and any function accessed by the new ref.func instruction. With this CL, we change the caching scheme an do the caching per signature. Thereby we can guarantee that any export wrapper which potentially exists can be stored in the cache. For cctests which use wasm-run-utils, we don't know the size of the cache anymore ahead of time. However, we assume that no more than 5 signatures will be used in any cctest. If this assumption is not true, we can just adjust the number. The cache is now accessed in all code paths where we need an export wrapper.
