Add microdroid specific sepolicy
Microdroid will have a separate sepolicy, apart from the core policy.
This is the first step; For now it's a simple copy of system/sepolicy.
For the future work, it will be stripped.
Bug: 189165759
Test: boot microdroid and see selinux enforced

+# Maps an arbitrary tag [TAGNAME] with the string contents found in
+# TARGET_BUILD_VARIANT. Common convention is to start TAGNAME with an @ and
+# name it after the base file name of the pem file.
+#
+# Each tag (section) then allows one to specify any string found in
+# TARGET_BUILD_VARIANT. Typcially this is user, eng, and userdebug. Another
+# option is to use ALL which will match ANY TARGET_BUILD_VARIANT string.
