Fix fallback parsing logic for legacy location events

* Fix various changes following MatrixSDKCrypto update (not linked here)

* Fix crash caused by unexpected ffi result when processing to device events

* Fix broken secret recovery following uniffi change
- previously the UserIdentity used to be defined through the UDL file and the order of the userSigning and selfSigning keys were different from the place where they were implemented
- switching from the UDL to the uniffi macro switched them back to the correct order, but that didn't cause any breaking changes api side
- as a result secret recovery would fail as the secrets wouldn't match for user and self signing

* Adopt safer to device event sync result handling

* Bump MatrixSDKCrypto to v0.3.11

* Fix unit tests

* Device dehydration v2
- add support for device dehydration v2 i.e. `org.matrix.msc3814`
- implement rest client methods and models
- implement flows for creating and storing the dehydrated device pickle in in 4s as well as recovering it to use for device rehydration
- implement methods for creating, retrieving, deleting dehydrated devices as well as consuming the messages stored on the backend in between sessions
- delete previous implementation

* Bump MatrixSDKCrypto to 0.3.12 - adopt latest API changes and URL encode the deviceId when requesting dehydrated device events

* Address PR review comments

* Attempt to fix the CI

* Drop down to Xcode 14.2 in an attempt to fix the linting
