App: UISI AutoReporting

[langleyd]

Accompanies SDK PR matrix-org/matrix-ios-sdk#1386
Resolves #5017

What's in this PR

• Similar to the web implementation this checks all decryption attempts(excluding during initial sync) and if it fails it then allows a grace period before triggering a report if it has not succeeded since the initial attempt. I used the grace period set on android of 30 seconds, possibly more suitable for mobile vs the 5 seconds on web.
• Similar to the android implementation it creates a UISI detector that detects the reports and a separate auto-reporter that reports them, avoiding duplicates(based on sessionId) and spacing out requests(I used the web value of 60 seconds)

TODO

• Android may be sending false positives as is checking isEncrypted but not clear event here. Open issue and fix. It's implementation could also be a bit more in line with web in just monitoring decryption attempts. Update UISI Auto-Reporting to match Web/iOS implementation element-android#5596
• Add response URL
• Test matching RS works

@pixlwave I extracted the common common code for sending reports from the app in case it's useful for your needs.

Nice work!

Otherwise looks good to me in terms of interoperability with web and android. I'm not clear on how most of these UI changes relate to this PR, is that separate work that accidentally got added to this branch?

One thing that'd be good to add here: if the description field contains the recipient_rageshake URL on a second line, it'll show up linkified in the github issue body so it's a lot easier to cross-reference sender and recipient rageshakes. See https://github.com/matrix-org/matrix-react-sdk/blob/develop/src/stores/AutoRageshakeStore.ts#L149
