NachoSoto 0bff3f65fe Sendable support (#1795)
Fixes [CSDK-379] and https://github.com/RevenueCat/purchases-ios/issues/1041#issuecomment-1206445939

[CSDK-379]: https://revenuecats.atlassian.net/browse/CSDK-379?atlOrigin=eyJpIjoiNWRkNTljNzYxNjVmNDY3MDlhMDU5Y2ZhYzA5YTRkZjUiLCJwIjoiZ2l0aHViLWNvbS1KU1cifQ

### Main changes:
- `Sendable` conformances to all types that are thread-safe
- `@unchecked Sendable` for types that the compiler can't enforce, but with documentation as to why
- Made classes that aren't mocked `final` (note that this doesn't change the API, because none of these were `open` to begin with)
- Made some classes thread-safe that weren't (like `DeviceCache`)

For the non-`final` `class`es, I've actually managed to compile the SDK with all of them as `final` and `Sendable`, to make sure that making them `@unchecked Sendable` didn't hide any other issues.

### Future improvements:
