Optimize fmha fwd decode & prefill for gfx950 (#2641)

Browse Source 
* Fix for fwd/bwd kernel build filter

* fix bwd code

* save an example for __bf16 type

* temp save, waiting for debug

* tempsave, fmha_decode

* temp save, change all instance to 1wave

* fix async copytest bug

* Add block_sync_lds_direct_load utility

* fix the s_waitcnt_imm calculation

* Improve s_waitcnt_imm calculation

* fix vmcnt shift

* add input validation and bug fix

* remove unnecessary output

* move test_copy into test

* temp save

* tempsave

* compile pass

* tempsave, trload+asyncload done

* tempsave. asynccopy+trload sanity checked

* remove unnecessary features

* fix the lds alignment caused performance regression

* enable prefill overload operator().

* remove all lds bankconflict with xor layouts

* enable larger tile size; upgrade xor pattern

* upgrade prefill pipeline; simple iglp; consistent data produce and consume order

* small refactor

* Load Q through lds, implement xor;

* add vmcnt guard before load ktile

* Add v_permlaneb32 for block_reduce. Disable it as it will cause un-coexecutable packed math in FA

* Add XOR fold strategy for hdim<128, but perf dropped; disable it by default; wait further perf debug

* add __restrict__ to tr load

* merge fa_decode pipeline into fmha_fwd api

* remove unnecessary files; rename some files

* Remove unnecessary changes

* bug fix, clang format;

* remove non-necessary change

* fix clangformat with 18.1.3

* fix bugs

* fix bug

* fix bug on non-gfx950

* fix bugs in gemm

* fix bug in pki4

* tempsave, update the blocksync functions

* change the warp setting for hdim32 fmha fwd

* clang format

* fix conflict. disable all v-col instance for fmha fwd

* Fix the bug

* clang format
