[CK] Add fwd conv group merging to v3 conv instances
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
## Proposed changes
Added conv group merging to the (universal) V3 fwd conv pipeline. The
new instance improves fwd conv performance when the number of
input/output channel per group is low.
On MI300 (`gfx942`) we get
| CK prof command | Baseline (TFLOPS) | V3 group merging (TFLOPS) |
