Improve preprocessor (#2579)

* Update documentation for 'Invoke-Preprocessing' Script Tool

* Improve Compile Script a bit Deduplicating a lot of un-needed pre-fixes - Improve implementation for 'Invoke-Preprocessing' Script Tool

* Fix RegEx in 'Invoke-Preprocessing' Script Tool

* Result of Preprocessing

* Update Replace Regex for Code Formatting in 'Invoke-Preprocessing' Script Tool

* Result of Preprocessing

* Update Exclude Files List for Preprocessing in 'Compile.ps1' Script

* Remove Extra Whitespace in some place for 'Invoke-Preprocessing.ps1' Script Tool

* Simplified and Improved the Exclude List Validation Step in 'Invoke-Preprocessing.ps1' Script Tool

* Restore 'workingdir' variable when using '-Run' Parameter with 'Compile.ps1' Script

* Revert "Update Exclude Files List for Preprocessing in 'Compile.ps1' Script"

This reverts commit 674ab0308b.

* Result of Preprocessing
