Save PackageDexUsage on PMS shutdown

This ensures that we persist the in memory data between restarts (makes
testing much easier).

(cherry picked from commit 14876bd21a4a4e7d78d36f910493269f14b2e905)

Bug: 64151900
Test: Manual, flash + restart + check the dex usage file

(cherry picked from commit 6ef7f0b8c6e72e849a220513425a9fd37804af90)
