Change all block pointers to tensor pointers Block pointers are for nvidia TMAs. They are useful for regular loads as well but not well supported. Also cleaned up some code I came across along the way and updated comment at the top.
Add support for layouts commonly used by users. Add option for varlen / thd layout to specify equal context lengths for all batches. Also often used by users.
Set SM scale multiplication to a constexpr. Minor asm improvement. Changed acc scaling to adjust for softmax division to multiplication with reciprocal. ~10% perf improvement.
