CPU Performance/Testing improvements (#1055)

* First pass of render-test refactor.

* Make window construction a function that can choose an implementation.

* Remove OpenGL as currently has windows dependency.

* Disable Vulkan as Renderer impl has dependency on windows.

* Pass Window in as parameter of 'update'.

* Add win-window.cpp as was missing.

* Fix warning on windows about signs during comparison.

* * Added mechanism to add random arrays as buffer inputs and select type
* Improved RenderGenerator to generate more types, and to be more careful around int32 ranges.
* Added support for security checks (for Visual Studio C++)
* Disable Execption handling being on by default when compiling kernels
* Added a 'Group' version of the entry point that will evaluate all threads in a group in a single call. In test code use this method if available.
* Added -compile-arg to be able to pass arguments to the compile within render-test

* Add documention for the _Group execution feature.

* Fix some typos in cpu-target.md
