Description
As concluded here https://github.com/PowerShell/PowerShell/issues/25953
The ValueFromPipelineByPropertyName parameter attribute should not be used with the ValueFromPipeline parameter attribute because it would not have any effect (the ValueFromPipeline attribute overrules the ValueFromPipelineByPropertyName attribute).

Research direction

Implement a rule for parameters using both ValueFromPipelineByPropertyName and ValueFromPipeline, and verify that the rule reports this redundant combination without flagging valid usage.
