AV1115: Exclude "and" from enum members with [Flags]

[bart-vmware]

It's generally fine to use "and" in enum member names to indicate the combination of multiple flags. For example:

[Flags]
public enum DiscoveryMode
{
    Register = 1,
    Query = 2,
    RegisterAndQuery = Register | Query
}

In cases like this, no warning should be reported.
