* add gitignore
* host tensor: allow generating sequentially increasing value in a given dimension
* gridwise gemm v3r1: allow distinct K0/K1 values for A/B block descriptor
- remove dangling header include
- modify example gemm_xdl accordingly
- infer KPack value from M/NPerXdl
- device conv2d fwd: update parameters accordingly for the underlying gridwise gemm v3r1
(API for conv2d fwd stays the same for now until we decide to expose individual K0s for activation and weight)
* add LDS data dump utility
* profiler: reflect API change for distinct K0/K1 for A/B matrices
* profiler: add conflict-free LDS write FP16 kernel instances
* fix accidental perf regression
* address feedback; cosmetic changes
* clang-format for new files
* format
