Feature/early depth stencil (#727)

* First pass support for early depth stencil.

* Add a simple test to check if output has attributes.

* Use cross compilation to test [earlydepthstencil] on glsl.

* If target is dxil, use dxc to test against.
Add hlsl to test earlydepthstencil against.

* * Added spSessionHasCompileTargetSupport
* Made slang-test use spSessionHasCompileTargetSupport to ignore tests that cannot run
