feat: App Keys API v2 (#10140)

# Which Problems Are Solved

This PR *partially* addresses #9450 . Specifically, it implements the
resource based API for app keys.

This PR, together with https://github.com/zitadel/zitadel/pull/10077
completes #9450 .

# How the Problems Are Solved

- Implementation of the following endpoints: `CreateApplicationKey`,
`DeleteApplicationKey`, `GetApplicationKey`, `ListApplicationKeys`
- `ListApplicationKeys` can filter by project, app or organization ID.
Sorting is also possible according to some criteria.
  - All endpoints use permissions V2

# TODO

 - [x] Deprecate old endpoints

# Additional Context

Closes #9450
