This kernel is a clone of 'GridwiseElementwise_1D'

* modify comment

* trim unnecessary check

* add gemm spec in kernel name

* add TNTT gemm_gemm + atten kernel instances

* refactor attention padding to better fit in unit tests

This streamlines usage where "ResetNaNToMinusInf" is now hidden from user facing device op.
Also added compile-time conditionals that load OOB value as NaN only after padding is enabled

* add adhoc padding test for atten

* shrink input value range for attention kernel validation to avoid occasional error by 1e-3

Still unsure whether this kind of deterministic floating point accurary issue is expected
or not. May want to try exact same approach as the GPU kernel in the host reference
GEMM+Softmax+GEMM function to see if the accuracy discrepancy goes away. Until then,
shrink the input value range as it is less likely to produce errors of around ~1e-3.

* attention kernel proper granular padding for all 4 dims

* IsSupportedArgument checks

* test more padded cases

* block PadK specialization in attention kernels

* workaround clang crash for gfx908

(gfx908 only) workaround for compiler crash in fused kernels on mainline #9110; #10738 seems ok
error message was "fatal error: error in backend: Error while trying to spill VGPR0 from class
VGPR_32: Cannot scavenge register without an emergency spill slot!"
this fall back to less ideal way of handle NPadding in fused attention kernel

* comment out kernels giving wrong results on MI100; MI200 doesn't seem affected

* add gemm_gemm TNNT instance

* sanitize Gemm1KPack

* disable instances that failed validation on mi100

* Update Softmax device operation interface.

* Update ckProfiler.

* Update Softmax UT.

* Update example.

* Client example.

* Clang format
