[M108 Migration] Add ewk apis to support functionality for Permissions.query JS api

At javascript side, permissions.query() is used to query the exisiting
permission status granted for an origin. The query has to be passed to
web browser to get the status, and hence there is need for introducing
new ewk apis :

ewk_view_user_media_permission_query_callback_set
ewk_user_media_permission_query_origin_get
ewk_user_media_permission_query_device_type_get

Web Browser returns EWK_USER_MEDIA_PERMISSION_QUERY_RESULT_{ASK|GRANTED|DENIED}
enum value, based on which blink::PermissionStatus::{ASK|GRANTED|DENIED} status
is returned to blink.
