feat: Include full module path to structs in abi

[spalladino]

Continues the work from #2266 and prepends the full module path to struct type names in the ABI. The name is composed as package_name::module_1::...::module_N::struct_name.

For example:

    {
      "name": "entrypoint",
      "functionType": "secret",
      "isInternal": false,
      "parameters": [
        {
          "name": "payload",
          "type": {
            "kind": "struct",
-           "name": "EntrypointPayload",
+           "name": "noir_aztec::entrypoint::EntrypointPayload",
            "fields": [
              {
                "name": "flattened_args_hashes",
                "type": {
                  "kind": "array",
                  "length": 4,
                  "type": {
                    "kind": "field"
                  }
                }
              },

Note that the crate_name added to CrateData is optional, since some instantiations of crates seem to be coming from not-a-package. Also, I was unsure as to emit the name of the package or the name of the dependency as registered in the contract package TOML. I decided to go with the former, since this ABI may be consumed from a location that doesn't know the mapping from dependency names to packages.

Now, if this feels like we're spreading too much data across internal types, I'm fine closing this PR and looking for an alternate solution.

Fixes #2238

Yeah, this feels like we're being leaky here. I need to look deeper than just the diff to see if this can be built up without cloning strings everywhere.
