Batched strided GEMM: C = alpha * A * B + beta * C

The views must be pre-permuted so that their dimensions are grouped as (batch-last canonical order):

• A: n_lo dims, then n_sum dims, then n_batch batch dims
• B: n_sum dims, then n_ro dims, then n_batch batch dims
• C: n_lo dims, then n_ro dims, then n_batch batch dims

Dimension sizes must match across operands within each group.
