Add app name and device name to window title

[huntie]

Summary

Note

Depends on #86 and facebook/react-native#45250.

Updates the rn_fusebox entrypoint to update the window title if the device returns identifying metadata via ReactNativeApplication.metadataUpdated. This signals the current app name and device name to the user! 🎉

Resolves T165849560.

Note

Known issue — ReactNativeApplicationModel is mounted within the Welcome panel, meaning this behaviour won't trigger if opened to another panel. This needs to be relocated in a later PR — likely having some model within the entrypoint inherit from this (or however the data flow can work). However, I want to land this change (see #88 for where we do make use of this in RNWelcome.ts) so we have incremental progress.

Test plan

Connect to Android and iOS after facebook/react-native#45250.

Upstreaming plan

• This commit should be sent as a patch to the upstream devtools-frontend repo. I've reviewed the contribution guide.
• This commit is React Native-specific and cannot be upstreamed.

Can you try making ReactNativeApplicationModel part of the SDK? I believe this way it should start automatically, together with other required models, such as RuntimeModel:

@hoxyq I can do 👍🏻 Alright if I stack this on top of #88?

Oh, I think I was wrong, its probably better to register model in rn_fusebox.ts, the way we do it for FuseboxClientMetadata model:

Model initialization logic is refactored in #90
