Utils: Adapt FindIndizes with new property PROP_NOT to invert the mat…

…ching

- 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
