Add Compress_apk property to android_app_import

This change adds a new boolean property, Compress_apk, to
the android_app_import module type. When set to true, the output APK
will be compressed using gzip. This can reduce the size of the
installed APK, saving storage space.

This functionality is the same as the LOCAL_COMPRESSED_MODULE variable
in Android.mk builds.
