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: - https://twitter.com/nachosoto/status/1557139992056500224?s=21&t=arWdvEzTIFANBvwqQ0vPiA - https://twitter.com/nachosoto/status/1557141944777592832?s=21&t=arWdvEzTIFANBvwqQ0vPiA - https://twitter.com/nachosoto/status/1557143374922059776?s=21&t=arWdvEzTIFANBvwqQ0vPiA ### Depends on: - #1794 - #1804 - #1806 - #1807 - #1808 - #1813 - #1822 - #1823 - #1824 - #1825 - #1826
