Expose event interface. fixes #2733

[Chaostheorie]

Expose tauri::event and rename tauri::event::Event to EmittedEvent. Temporary fix for #2733. This is supposed to be a POC for my internal use until #2733 is resolved in v1.x.

Thanks for taking the time to fix this.

You need to:

1. rename EmittedEvent to Event and remove any mention of EmittedEvent
2. rename Event to RunEvent, obviously this will clash with the runtime::RunEvent import in core/tauri/src/app.rs so you're just gonna need to rename the import and not the original struct, something like this use runtime::RunEvent as RuntimeRunEvent

[amrbashir]

You also need to add a changefil in .changes folder and don't forget to mention the breaking change Event -> RunEvent

[Chaostheorie]

What would be the appropriate level for this change? Semver would dictate to use major since the API is changed, but semver doesn't seem to be enforced for next.

[FabianLars]

It's not enforced because of the prelease stuff, so patch is fine, as this needs to land in v1 anyway (mainly because of the EventHandler fix)

[Chaostheorie]

There seems to be a change request pending, but I can't figure out, what it is referring to.

@amrbashir your name appears in the UI, have I overlooked something?

[FabianLars]

@Chaostheorie Don't worry, that's just the UI not updating until he approves the PR. As far as i can see you got everything he requested so far 👍

[Chaostheorie]

@amrbashir and @FabianLars thank you for the great help and explanations.
