PR 2596 added deterministic CP runs to the L3 FA-versions matrix, multiplying
CP wall time across every FA version and causing CI timeouts (pipeline
50243000). Run CP tests once per arch instead, picking the FA version each
arch's CP code path actually supports:
- sm90 (H100): FA3 3.0.0b1 - context_parallel.py is FA3-only on Hopper
(use_flash_attn_3 threaded throughout, FA4
not wired in; pad_between_seqs gated on
use_flash_attn_3 at lines 1038, 1366)
- sm>90 (B200): latest FA4 - FA3 is not built/installed for sm>90
Non-CP test_attention.py still runs for every FA version in the array.
Also drop FA 2.7.3 from the sm90 list (no longer maintained as a target)
and bump the FA4 pin from 4.0.0b8 to 4.0.0b11. b8 has an SM90 backward
kernel bug fixed by upstream PR NVIDIA#2513 in b11
(get_smem_store_C() got multiple values for argument 'transpose').
