feat(core): Add getSdkMetadata to Client (#6643)

Add a new method to the `Client` interface: `getSdkMetadata`.
We can use this method in the Replay package to avoid accessing `client.getOptions()._metadata`, which previously caused broken CDN bundles which we hot-fixed with #6600. This change now properly fixes this issue by simply not accessing this "private" field anymore.
