ref: Use Swift integrations

[noahsmartin]

Adds a new protocol for integrations that takes dependencies as an input. For the easiest migration conformers of the protocol can satisfy the Dependencies associated type with just typealias Dependencies = SentryDependencyContainer. This PR shows how it can be used to make the dependencies just define the minimum necessary dependencies so it can be easily mocked in tests. There are a few benefits to this over the current objc protocol:

• The protocol defines a failable initializer rather than a function returning a boolean. This means properties in the integration can be let constants rather than vars with default nil value. Making these immutable with help with a lot of swift properties like thread safety, and remove the need from handling null cases that should be unreachable.
• The associatedtype for dependencies decouples the SentryDependencyContainer from the integration, so each integration only defines the dependencies it needs and doesn't have a reliance on a particular type providing those dependencies.
• No need for @objc in the integration classes
• Integration names are explicitly provided rather than inferred from class names

Honestly, I'm unsure about this approach. I will have another look tomorrow, but here's what I already found.

[philipphofmann]

Sorry that it took so long. I had to give this some thought.

Thanks, I still found a view things, but we're getting close to a LGTM
