Purpose of this PR

Why is this PR needed, what hard problem is it solving/fixing?

---

This PR backports some fixes from this PR

This includes:

• Fixing Input attachments on Metal Editor
• Enable RenderPass on some Decal techniques and fixed DBuffer to render properly if UseRenderPass is enabled
• Disabled RenderPass on DepthOnly pass
• Backporting some of the API to control Transient Input Attachments to fix DepthNormals pass (as currently if Input is used - all of the attachments will be transient and we need to disable that for GBuffer2 when DepthNormals are used)

Testing status

Manually ran all of the tests suites with RenderPass enabled on all of the Renderers inside them
