[PATCH v4 1/3] vkd3d-shader/ir: Revert "Do not merge signature elements which have different interpolation modes."

[Conor McCarthy]

From: Conor McCarthy

This reverts commit b5c067b41a173e2ab252d5a3588f807c3ade5b2a.

The commit causes regressions in other shaders because unused elements
do not have an interpolation mode.
