Some input varyings might not be written by any of the active stages
preceding the stage reading the varying (e.g. gl_Layer should be set
to 0 when not written by vertex/geometry shaders). In this case, we can
insert a dummy varying attribute returning zero. This is actually what
the code intended to do, but 2 things were missing:
1. formats[NONE] is not mapping to the CONSTANT0 format
2. the offset and strides should always be set to 0 when using a
CONSTANT0 attribute
All of this is needed to have the input attachments working. Indeed, we
use the nir_lower_input_attachments() pass which lowers input attachment
loads to texel fetches, and the txf operation is passed the layer_id
in its 3rd coordinate.

Fixes several problems in the pan_blit() logic:
1. We actually need the reciprocal of the depth scaling in z_scale (maybe
we should rename this field z_scale_rcp to make it clear)
2. When Z end < Z start we should remove one to the cur_layer/layer_offset
instead of doing it on the last_layer field, otherwise there's an
off-by-one error
3. The Z src offset should be adjusted to account for scaling. If we don't
do that we won't sample from the right layer when upscaling.
