Summary:
This diff converts the CrashReporter plugin to Sandy. The main driver is that it allows us to fix the connection management of logs in a next diff.
There are few changes to highlight:
* A bunch of the old unit tests are removed, as they primarily verified that persistedState abstraction works, a concept that doesn't exist anymore with Sandy (as a result all the logic in error handling and crash reporter plugin has become a lot more trivial as well)
* Added additional unit tests to verify that the integration with notifications from Sandy, and the integration of crashes in combination with CrashReporter plugin works (this wasn't the case before)
* Plugin errors were always suppressed in production builds of Flipper. However, that makes error reporting pretty pointless in the first place, so enabled it by default, but made it a setting in case this results in too many errors suddenly.
* The integration with clicking OS crash notification -> bringing the user to a sensible place _doesn't_ work, but it didn't work before this diff either, so will address that later
* This doesn't upgrade the Crash reporter UI to sandy yet, will do that later in a separate diff
Changelog: Crash reporter will now report errors triggered from the device / client plugins by default. This can be disabled in settings.
