plat_sepolicy_vers.txt stores the version of vendor policy. This change adds sepolicy_vers module to migrate plat_sepolicy_vers.txt to Android.bp. - Device's plat_sepolicy_vers: should be BOARD_SEPOLICY_VERS - Microdroid's plat_sepolicy_vers: should be PLATFORM_SEPOLICY_VERSION because all microdroid artifacts are bound to platform Bug: 33691272 Test: boot device && boot microdroid Change-Id: Ida293e1cb785b44fa1d01543d52d3f8e15b055c2
