Philip P. Moltmann 66c5a8d207 Dump activities that handle when USB devices get plugged in
When a USB device or accessory gets plugged in the system might
automatically start activities that have a device/accessory filter set
to include the plugged in USB device.

Unfortunately we seen too many apps setting too broad of a filter and it
annoys the user that this apps wants to start every time the device gets
plugged in.

This change dumps the acitivity names and their filters so debugging
such issues is much easier.

To do this, there is some mild refactoring:

1. Split packageMatchesLocked into
- getDeviceFilters to resolve all device filters
- getAccessoryFilterer to resolve all accessories
- Check if a filter matches after resolving all filters. This is no
  performance issue as usually there is only one or two filters per
  activity.

2. Split queryIntentActivitiesForAllProfiles into
- A per user part, so that we can use the exact same intent-resolution
  code for the dump-code
- And a loop over the per user part

Test: adb shell dumpsys usb
      + incident_report usb
      + verified that the output is as expected
