Make Path and LiteralPath parameters work like they do for Item cmdlets

[sdwheeler]

Summary of the new feature / enhancement

The Path paramter needs to allow pipeline input and the LiteralPath parameter need aliases and pipeline input. We should match the configuration of the Item cmdlets.

-Path

Aliases : {}
ValueFromPipeline               : True
ValueFromPipelineByPropertyName : True

-LiteralPath

Aliases : {PSPath, LP}
ValueFromPipeline               : False
ValueFromPipelineByPropertyName : True

Proposed technical implementation details (optional)

The current implementation of these parameters does not match.
