Description

Currently, error codes in generated ErrorGroups class are static readonly int, because we calculate them at runtime with GetFullCode.

However, this prevents pattern matching. The following does not work:

if (e is IgniteClientConnectionException { Code: ErrorGroups.Client.ClusterIdMismatch })
{
    ...
}

Compiler error: [CS0150] A constant value is expected.

Since we use code generation, it is easy to compute error codes at compile time and use constants to make things nicer for the users.
