Fused attention (#345)

* initial stub for gemm_gemm_xdl_cshuffle

* set up example code

* compiles

* prevent integer overflow

* harmonize interface between ref_gemm and ref_batched_gemm

* batched_gemm_gemm

* fix example

* host tensor gen: diagonal pattern in lowest two-dimensions only

* make c descriptors containing only integral constants

* clean up

* add BlockwiseGemmXdlops_v2 while exploring an unified approach

* implement proper interface

* tidy up example

* fix compilation warnings

* coarsely controlled 2nd gemm padding

* remove rocm-cmake's hard requirement for certain revision

* clang-format

* resolve merge conflict

* fix compilation error on gfx10

* adds acc0 elementwise op to interface

* attention host validation

* add blockwsie softmax v1

* iteratively update softmax+gemm

* transpose both gemm0 and gemm1 xdl output so as to avoid broadcasting softmax max/sum

* add init method for easier debugging

* do away with manual thread cluster calculation

* generalize blockwise softmax interface

* row-wise softmax sum & max

* format

* rename to DeviceBatchedGemmSoftmaxGemm

* add gemm_softmax_gemm instances and tests

* comment
