Pull request overview
This PR enhances flash decoding for attention fusion by introducing automatic split calculation and support for padding when sequences don't evenly divide. Previously, users had to manually specify the number of splits via environment variable, and sequences had to be evenly divisible. Now, the system can automatically determine optimal splits based on configurable parameters (minimum chunk size, maximum splits, and threshold), and padding is applied when necessary to handle arbitrary sequence lengths.
Key changes:
- Automatic calculation of optimal splits for flash decoding based on sequence length and configurable constraints
- Support for padding K and V tensors when sequence length is not evenly divisible by number of groups
- Refactored common split dimension logic into a shared
split_factor.hppheader to eliminate code duplication

Motivation
Currently, the number of splits used for flash decoding must be specified by an env var, and the splits must evenly divide into the sequence length. This PR refactors the
split_dimand family functions used throughout the code and uses the same functions for choosing best splits for flash decoding.This PR lets the user set the minimum split size, the threshold for splitting, and the max number of splits as well. These defaults are temporary and can and will be improved with experimentation, coming next. Flash decoding still has to be enabled by the user, either using the enable env var, or setting the number of splits manually, which I have also kept for now.
