type Collation

Collation is a generic implementation of the Collation interface that supports any collation in MySQL by performing the collation operation directly on a remote `mysqld` instance. It is not particularly efficient compared to the native Collation implementations in Vitess, but it offers authoritative results for all collation types and can be used as a fallback or as a way to test our native implementations.
