TMDM-7557: "Oracle doesn't support EQUALS operator between 2 fields when one includes large text column in database"

Moves matching statistics to EE module.
Use CLOBs only when field length exceeds max varchar size (currently: 255).
IncompatibleOperators no longer replaces EQUALS with STARTS_WITH if database column size does not exceed 255.
Don't include in integrated matching types where key's max length is lower that UUID's max length.
STARTS_WITH substitution is no longer done when performing a field to field comparison.
Fix "Unvisited predicate: com.amalto.core.query.user.Predicate$And@7d54fd2e" message during user query dump.
