PipeScript should simplify Search-PipeScript

[StartAutomating]

Since many transpilers could depend on searching portions of an abstract syntax tree of script, Search-PipeScript should simplify this for all transpilers.

This should be able to search:

• A ScriptBlock
• A File
  • .ps1 files should be searchable as a -ScriptBlock
  • .ps files should be searchable as a -ScriptBlock
• Text (using Regex)

For [ScriptBlock] input, Search-PipeScript should:

• Allow searching by type
• Allow searching by shortened type (assuming the namespace)
• Allow searching by type name regex or wildcard

For [string] input, Search-PipeScript should:

• Allow searches by Regular Expression

Results should be returned with a consistent property bag shape and typename.
