* Run ctest with --output-on-failure

* Fix synchronization issues in bwd pipelines

The bwd kernel reuses the same area of LDS for ds (SGrad), bias and
dbias (BiasGrad). This means that there must be block_sync_lds between
loading one tensor and storing another to the same area.

Heavy instructions like MFMA/WMMA and global loads are executed between
reuses of the same memory so in MOST cases loading is finished by all
warps before storing is started. However, sometimes warps progress at
different speeds.
Running the tests multiple times and, preferably, with multiple
processes on the same GPU helps to trigger this issue:

bin/test_ck_tile_fmha_bwd_bf16 --gtest_repeat=-1 --gtest_shuffle --gtest_throw_on_failure
#2851)

* [CK_TILE] Add sequence padding and variable length support in fmha (and v3)

 - Group Mode Padding: Introduces the `-s_qpad` argument to support
   physically padded layouts. Kernels now use padded start pointers
   (`seqstart_padded_*_ptr`) for memory addressing.

 - Batch Mode Variable Length: Adds `-q_eff_lens` and `-kv_eff_lens`
   arguments for efficient processing of variable-length sequences by
   passing cumulative effective lengths (`cu_seqlen_*_ptr`) to the kernel.

 - FMHA examples: Support padding and variable length both in
   group and batch mode. Dispatcher is updated as well (dispatch to
   kPadSeqLenK enabled pipeline).

 - New padding test cases: Add padding test cases to `smoke_test_fwd.sh`,
   and add benchmarks to `benchmark_fwd.sh` and `benchmark_fwd_v3.sh` as well.
   These test cases and benchmarks that specifically validate/benchmark the
   new padding and variable-length functionalities in both group and batch modes.

* [CK_TILE] Fix build error in fmha unit tests
