ANR Detection Improvements

[Angelodaniel]

As of today Unity has their own watchdog thread that is checking if ANR's are happening.
We've disabled leaning on the Android SDK for the ANR detection but the Android SDK has progressed over time to have more types of ANR detection with their own pros/cons.

So there is another ticket that will be responsible for tagging the Mechanism to a Sentry event which is already great.
But we also need to have more precise ANR detection on this, hence the ticket.

@bruno-garcia, @romtsn & @bitsandfoxes have been in conversation about this.

Hey Team, this is still ongoing or did we improve things over time? @bruno-garcia @romtsn @bitsandfoxes

What would that be?
