[DotNet] Create Utility class for Regular Expression (#1873)

* Create RegExpUtility class with methods

Created
* GetMatches( )
* MatchEnd( )
* GetFirstMatchIndex( )
* Split( )
* SanitizeGroups( )

Removed
* GetMatchesSimple( ): In JavaScript was only used in GetMatches method, but this method already existed in .NET, and it did not need GetMatchesSimple, so I removed it.
* GetSafeRegex( ): In JavaScript It was only used in QueryProcessor class, which, in .NET, didn't need it.
* IsMatch( ): in .NET is a Regex function so I didn't need to create it
* GetNextRegex( ): It wasn't use anywhere in the code
* GetClosePos( ): It was only used in GetNextRegex method, which I removed

* Add all methods into RegExpUtility class and migrate ConditionalMatch class, and RegexExtensios.cs methods too.

We added four more methods from RegexExtensions.cs:
* IsExactMatch( )
* MatchExact( )
* Match End( )
* MatchBegin( )

And removed one:
* GetFirstMatchIndex( ): It had not use anywhere in dotnet

We change MatchEvaluator( ) to ReplaceMatchGroup( ) because that name was more descriptive

Also, we moved ConditionalMatch class from Microsoft.Recognizers.Text.DateTime to Microsoft.Recognizers.Text.Utilites, so the methods we moved before do not break the existing references.

Finally, we imported Microsoft.Recognizers.Text.Utilites everywhere the code had errors because of the classes and methods migration.

* Changing folder name to fix casing
