Accompanies firebase/firebase-functions#1099. With this change, users using the supported version of the Firebase Functions SDK will be able to bypass existing/default cors settings to call the emulated HTTP/callable v2 functions.

I think we also need to default cors to true to keep parity with V1.

| Whoops. I see where we did & still do default to CORS true for Callable functions in v2. |

* Un-hide CF3v2 (#4525) * Resolve relative paths for local extensions (#4529) * Improve error message when parsing function source fails. (#4527) Previously, an invalid function source would show error message like this: ```bash $ firebase deploy --only functions i deploying functions ... Error: Failed to parse backend specification: - YAMLException incomplete explicit mapping pair; a key node is missed; or followed by a non-tabulated empty line at line 1, column 65: ... function source: ReferenceError: aa is not defined ``` This is surprising - a YAMLException? A backend specification? Often times, the full error message would curt short, and debugging the issue required the user to carefully inspect the debug log. We improve the error message to the following: ```bash $ firebase deploy --only functions i deploying functions ... Error: Failed to load function definition from source: Failed to generate manifest from function source: ReferenceError: aa is not defined ``` We hid the YAML portion of the error and make sure to relay the full error message returned from the underlying Functions Control API (i.e. the serve responsible for loading and advertising the `functions.yaml` baked into the Functions SDK) * Set `enableCors` debug feature when emulating CF3 functions. (#4528) Accompanies firebase/firebase-functions#1099.

As suggested by @jhuleatt, we add a debug feature in the SDK to enable CORS setting (i.e. set CORS origin setting to allow requests from any origin) during function emulation to make emulator experience less painful. For example, given the following v2 https function:
Users would've had to add
localhost:XXXto the cors setting to make function emulation work. With the new debug feature (which the Functions emulator will enable), users won't need to make such change.Thanks @jhuleatt for pushing the idea for an excellent feature!
