Bluetooth: Add read remote version on startup and added to bt_conn_get_info

[Blackladder]

Add read remote version on startup and added to bt_conn_get_info.

Added remote features to bt_get_conn_info (and to the bt_conn_le_info struct)
Added remote version struct to bt_conn_info union.

If CONFIG_BT_TESTING is enabled:
-read_remote_version is called on connection
-bt_conn has an extra remote_version struct in the union
-bt_conn_get_info also gives remote version information

note: read_remote_features is already called on connection
