Subject: [PATCH] Add missing RTV to QuadReadTest XML (#3554)

The mesh shader path for QuadReadTest expects at least one render target. Without, the test framework attempts to clear a nonexistent RTV resource:

D3D12 ERROR: ID3D12CommandList::ClearRenderTargetView: Specified CPU descriptor handle ptr=0xCCCCCCCCCCCCCCCC does not refer to a location in a descriptor heap.

The commit in this PR simply adds an RTV, and will proceed through to test completion.

(cherry picked from commit a607ce605e3cc5b00337842f5cb32c8dcbb47c8f)
