Add AIDL enforce_permissions attribute

When set to true, this attribute will pass down the
-Wmissing-permission-annotation flag to the aidl compiler. It is
possible to declare a set of exceptions (for a graduable adoption). For
now, only Java is supported.

Test: build having the attribute enabled for frameworks/base
