Yunus Shaikh 14e56205cf fix(agc): leave a colour-drawn native stencil plane unproven until a plane fill
A native D32S8 target whose separate stencil plane a multisampled colour
target covers with a draw, unknown content, or another format or sample
count was refused at import, so sampling its depth failed as well. The
plane is now imported unproven: its host stencil is not taken from it,
depth sampling and depth-only draws continue, and a draw with a stencil
test or a sample of the plane refuses with the stencil alias text and a
line naming the colour target's state.

A later whole-plane fill proves the plane from the fill byte without
reading guest memory and clears the host stencil to it, provided a
colour target still over the plane absorbed that fill as the same R8
byte at the same sample count; otherwise the fill is refused.
