Update boot image profile

Compiled methods don't get any interpreter activity modifying their
hotness counters. This CL compiles more methods to prevented

Original set of profile is the updated profile with revised thresholds
for image classes. Here we used a 3% threshold.

Additionally, the CL adds imgdiag diagnosed methods that have dirty JIT
counters shortly after boot on the following apps:
system_server
com.android.systemui
com.android.phone
com.android.nfc
com.google.android.networkstack
com.android.bluetooth
com.google.android.apps.nexuslauncher
com.google.android.gms.persistent
com.google.android.as
com.google.process.gservices
com.google.android.gms
com.google.android.inputmethod.latin

Before:
Boot oat size: 32,800,596 bytes
Persistent app .art PSS: 19115K
Persistent app .art Private Dirty: 15356K
System boot .art PSS: 60948K

After:
Boot oat size: 37261124 bytes
Persistent app .art PSS: 12610K
Persistent app .art Private Dirty: 8740K
System boot .art PSS: 50735K

Private dirty savings for persistent apps: 7MB
Net RAM savings: 5MB (10MB dirty .art PSS, 5MB oat size incrase)

Bug: 134776403
Test: Reboot and inspect RAM usage
