OPC-UA: only support the encryption policy selected in config.
By default open62541 client accepts all supported policies, but in makes problem
when negociating with some servers while most clients seems to only support
one policy at a time.

Switch widget hides all subelements whose label do not match given
variable current value representation. For exemple if given variable type
is HMI_INT and value is 1, then elements with label '1' will be displayed.
Label can have comments, so '1#some comment' would also match. If matching
variable of type HMI_STRING, then double quotes must be used. For exemple,
'"hello"' or '"hello"#another comment' match HMI_STRING 'hello'.
