Remove the string type refactoring

It'll be Re-introduced as an analyzer following #66.
Add an analyzer/fix for verbatim & Regular strings

The analyzer add a diagnostic to regular strings ("Hello") and verbatim
ones (@"Hello") and the code fix suggest for each one to convert to the
other.

This code was a refactoring but converted to a code fix after discussion
in #93 following the decision of #66.
