Feature/renderer binding (#489)

* Dx12 rendering works in test framework.

* Turn on dx12 render tests.

* First pass at Resource and TextureResource/BufferResource types.

* Fix bug in Dx11 impl for BufferResource.

* Dx12 supports TextureResource and binds using TextureResource type, and all tests pass.

* Added TextureBuffer::Size type to make handling mips a little simpler.

* Small improvements to Dx12 constant buffer binding
Removed k prefix on an enum

* First pass impl of dx11 createTextureResource
Added setDefaults to TextureResource::Desc and BufferResource::Desc to simplify setup
accessFlags -> cpuAccessFlags
desc -> srcDesc

* Split out generateTextureResource - can produce the texture using createTextureResource on the Renderer.

* Added support for read mapping to Dx11
accessFlags -> cpuAccessFlags
First pass at using TextureResource/BufferResource on Dx11
Some tests fail with this checkin

* TextureResource working on all tests on dx11.

* Construct ResourceBuffers on Dx11 and Dx12 using utility function createInputBufferResource.

* First pass at OpenGl TextureResource

* Small fixes to dx12 and dx11 setup.
Gl working working using BufferResource and TextureResource

* Tidy up around the compareSampler - looks like the previous test was incorrect.

* Small documentation /naming improvements.

* Fix some more small documentation issues.
