Adding CTS for removing PII fields from data view in CP2

Adding two tests:
1. testDataView_projection_unrestrictedForLegacySdk which
ensures that the PII fields are visible in legacy (targeting <37)
Apps.

2. testDataView_projection_restrictedColumnsNotPresent which
ensures that PII fields are removed from apps targeting >= 37

*This is a new change with package name altered from ag/35458228
