Make Transforms management more akin to D3D9

This change removes Transforms as a Rendering Step and instead sets them
manually when calling appropriate Render call. Additionally, the
viewport is now set from -1 to 1 instead of original 0 to 1 to adjust
for Prism's expectations - this essentially accomplishes the same as
D3DContext.adjustClipSpace() method in D3D pipeline, matching D3D12's
clip space to OpenGL expectations.

Fix Depth Buffer clearing

In situations where we render a SubScene with depth testing enabled
Prism would often follow below pattern for clearing the RTT:
- set the RTT with depth test disabled
- clear the RTT
- re-set the RTT with depth test enabled

D3D12 assumed that when the depth testing is disabled then the Depth
Buffer should not be cleared even when it is present. This turned out to
not be the case, as D3D9 backend cleared the Depth Buffer even if the
testing was disabled. As such, in some scenarios (HelloViewOrder) we
missed a Depth Buffer clear which created visual bugs.

This change fixes above scenario and makes it so that Clear() can be
issued with clearDepth flag. If present and Depth Buffer has already
been created the Clear() will also issue a Depth Buffer clear.

Fixes HelloViewOrder demo not drawing the subscene properly and in
correct order.
