ref(flags): allow OpenFeature integration to track a single client

[aliu39]

All provider SDKs so far have the concept of a "client" class, which is used to connect to the server and query flags. Since clients can query multiple projects/environments by specifying a context, it is rare for an app to use >1 client.

I discussed with @billyvg and we want to stay consistent for all FF integrations, and focus on tracking one client. This means users should pass a client to the Integration, and we'll register hooks on that client, rather than globally.

Update 12/26:
For backwards compatibility, I think it's best to

• keep LD as-is: optionally takes a client. If one is not given, then hook into the global singleton.
• mirror this in OF, optionally taking in a client.

Updated setup code can be seen at: https://github.com/getsentry/sentry-docs/pull/12222/files
