Previously RollbackManager would only backup and restore the base apk
for a package. This change fixes it to backup and restore split apks as
well.
Adds a new test for rollback of packages built with splits.
Also, switch to using resources to distinguish between v1 and v2 of an
application instead of meta-data, given we use resources anyway now to
distinguish between split versions.
Bug: 124848643
Test: atest RollbackTest, with new test for splits added.

RollbackManagerService incorrectly ignores the package name passed to
getAvailableRollback and executeRollback.
This CL fixes the bug and adds a regression test. The infrastructure for
having multiple test apps in RollbackTest will also be useful for
testing rollback of multi-package installs.
Test: atest RollbackTest (with selinux disabled)
