Relabel various exported3_default_prop

This removes bad context names "exported*_prop". Property contexts of
following properties are changed. All properties are settable only by
vendor-init.

- ro.config.per_app_memcg
This becomes lmkd_config_prop.

- ro.zygote
This becomes dalvik_config_prop.

- ro.oem_unlock_supported
This becomes oem_unlock_prop. It's readable by system_app which includes
Settings apps.

- ro.storage_manager.enabled
This becomes storagemanagr_config_prop. It's readable by coredomain.
Various domains in coredomain seem to read it.

- sendbug.preferred.domain
This bcomes sendbug_config_prop. It's readable by appdomain.

There are still 3 more exported3_default_prop, which are going to be
tracked individually.
