Unlike staged installer check, we can't check if given APEX package is allowed to be updated at session creation time, since we don't have knowledge of the package being installed yet. Instead, the check is implemented in PackageInstallerSession#handleInstall. Like staged install check, allowed apex update check has similar exemptions (adb is allowed to update any APEX, `adb shell pm --bypass-allowed-apex-update-check` makes next install session bypass the check). In order to implement these exemptions, a new INSTALL_DISABLE_ALLOWED_APEX_UPDATE_CHECK flag that can only be set by system is added. PackageInstallerSession will skip the APEX update checks if INSTALL_DISABLE_ALLOWED_APEX_UPDATE_CHECK is set.
