Replace PowerShell codegen with C# (#656)

* Initial project

* Add CodeGen to solution

* Add DragonFruit 0.2.0-alpha.19174.3

* Remove unused after.UnitsNet.sln.targets

* All codegen scripts recreated

* Codegen: Minor whitespace fixes

* README: Minor fix

* Remove PowerShell scripts

* Update build script

* WRC: Remove codegen for tests

It was stepping on the toes of the new codegen and WRC should not generate test code anyhow.

* Remove submodules from csproj

* Minor cleanup

* Add initial WRC codegen

* Don't call WRC PS1 scripts

* WRC StaticQuantityGenerator exact match

* WRC QuantityGenerator OK

* WRC QuantityTypeGenerator OK

* WRC UnitAbbreviationsCacheGenerator OK

* Restructure folders

* WRC: Remove all .ps1 scripts

* Update build message for codegen

* WIP

* Improve xmldoc of Main method

* Add option --skip-wrc

* Remove dead codegen code in WRC

* Re-implement Support multiple abbreviations (#658)

Merge conflict had to be ported from PowerShell to C#.
UnitAbbreviationsCache now gets single entries with string arrays instead of multiple entries with single item arrays.
This is an improvement, but should be functionally equivalent.
