fix Enum not resolved in first level input arguments (#561)

* fix enumtypemapper not handling enums passed as input via variables
due to a missing ltrim not being carried over from the myclabsenumtypemapper the FQCN of the enum most of the time had a leading backslash resulting it not being found in the cache or duplication once with and once without leading backslash
excluding of enums is not done on the NS getClassList method but reather later in the AbstractTypeMapper so EnumTypeMapper can actually find Enums (this whole implementation was previously working by accident)

* remove php8.1 conditions
