dev-python/flash-attn: enforce CUDA build dependencies

The exact 2.8.3.post1 setup imports wheel and psutil during extension construction,
requires CUDA 11.7 or newer, and builds against PyTorch CUDA APIs. It also consumes
FLASH_ATTN_CUDA_ARCHS directly, so use that interface instead of an ignored PyTorch
variable.

dev-python/flash-attn: add 2.8.3_p1

dev-python/flash-attn: new package, add 2.8.3

Provides flash_attn_varlen_func, required by the TRELLIS sparse-attention path.
The sdist omits its CUTLASS submodule, so a second SRC_URI stages CUTLASS at
the pinned commit (== 4.0.0) into csrc/cutlass during src_prepare. MAX_JOBS is
held at 2: the backward hdim128/256 kernels OOM this host at higher job counts.
