This commit adds fake 31.0 prebuilt. The prebuilt is based on AOSP policy, but slightly modified so the set of types and attributes is a subset of real 31.0 prebuilt (sc-dev policy). Steps taken to make the fake prebuilt: 1) build plat_sepolicy.cil both on AOSP and sc-dev, with lunch target aosp_arm64-eng. 2) diff both outputs to find out which types and attributes don't exist. 3) remove all relevant files and statements. As a result, the following types are removed. artd artd_exec artd_service power_stats_service transformer_service virtualizationservice virtualizationservice_data_file virtualizationservice_exec Bug: 189161483 Test: N/A, will do after adding 31.0 mapping files.
