Having a simple Dear ImGui bridge is not just useful for the manual
tests, which do not have any other means to displays GUIs, but is
in itself an important exercise for the QRhi machinery.
Have a new manual test that exercises the built-in ImGui demo window.
Then use it in the displacement test for real, to replace the myriads
of key presses with on-screen sliders and checkboxes (with less code).

This test was created with a work around for a Metal tessellation
pipeline memory alignment issue. The workaround was to specify shader
stage in / out variable uv as vec3 rather than vec2. A recent patch to
correct Metal tessellation pipeline memory alignment has now allowed
this test to use vec2 for variable uv as originally intended.

If it's executable, it should specify how it's to be executed.

There is something odd when running on Metal: note how the uv
is vec3 instead of vec2, in order to make the vertex-tesc-tese
data to look like this:
struct main0_out
{
float3 out_uv;
float3 out_normal;
float4 gl_Position;
};
if out_uv was float2 we'd get some strange rendering results,
perhaps due to something related to alignment. But have no means
to investigate this further.
