makes app exploitation much harder on devices and OS's with MTE support https://source.android.com/docs/security/test/memory-safety/arm-mte#enable-mte-apps

Capy Reader runs fine for ~6 months for me on GrapheneOS with Memory tagging enabled for an app. Propose to enable it by default.

This change will affect:

  • Google Pixel's users with stock OS with Advanced Protection enabled
  • Google Pixel's users with GrapheneOS
  • Samsung Galaxy users in some near future
  • other devices with other OS's in some not that near future
