Add related 3 CTS tests for PackageInstallerSession in TEST_MAPPING

When developers change services/.*Install.*, core/.*Install.*, and
services/core/java/com/android/server/pm/.* files.  The following
CTS tests should be included.
* CtsAtomicInstallTestCases
* CtsPackageInstallTestCases
* CtsAppSecurityHostTestCases:android.appsecurity.cts.SplitTests

The above 3 CTS tests take a few minutes.
