Add bugreport pre-dump functionality
Allow apps to trigger the dump of certain critical data, e.g. data stored in short
ring buffers that might get lost by the time a bugreport is requested.
Then, a bugreport request can specify whether the pre-dumped data should be used.
Fixes: 205138504
Test: atest com.android.os.bugreports.tests.BugreportManagerTest
Ignore-AOSP-First: depends on changes (surfaceflinger) that cannot go into AOSP
