* vulkan: Switch MUL_MAT_VEC to 4 K per iteration for F16/32 Against mesa git, this shows a 4.8% performance improvement for tg128 on Qwen3.5-9B:BF16 on Intel BMG. Note that this breaks some tests until the last commit which fixes OOB A reads. * vulkan: Use aligned loads in mul_mat_vec when available Against mesa git, this shows a 3.3% performance improvement for tg128 on Qwen3.5-9B:BF16 on Intel BMG. * Make explicit that `num_rows` is <= `NUM_ROWS` in mul_mat_vec Mesa's UUB logic can't see through conditionals, limiting its ability to understand the bounds on the `num_rows` field in the cleanup run. Making it explicit that `num_rows` is, indeed, always <= `NUM_ROWS` helps mesa make slightly better codegen. Against mesa git, this currently shows a 1% performance improvement in tg128 on Qwen3.5-9B:BF16 on Intel BMG. * vulkan: Fix OOB A reads in MUL_MAT_VEC for odd sizes There was a TODO to fix the OOB reads from the A matrix which we do here. It is within performance noise (+<0.1%) in tg128 for Qwen3.5-9B:BF16 on Intel BMG.
