Utils: Adapt FindIndizes with new property PROP_NOT to invert the matching

[MichaelHuth]

• PROP_NOT can be set additionally to the other properties and also alone

• PROP_NON_EMPTY and PROP_NOT_MATCHES_VAR_BIT_MASK were removed as these are now obsolete

• adapted the argument checking in FindIndizes

• adapted call sites for FindIndizes that were using now obsolete constants

• added tests for setting PROP_NOT only

• Extended ConvertListToRegexpWithAlternations with required features, added tests

• adapted TestEpochRecreationRemoveUnsupportedUserEpochs
