[Codegen][GPU] Enable 3-stage pipelining with hipblaslt compute->write->read ordering (#22788)

3-stage uses different cluster ordering to maximize distance between
read and use. Stage definitions remain the same. The changes are mostly
trivial and the new pipelined code work out of box.

On MI300, the tracked gemm configs improve performance by 4.5% on
average for NN and NT layouts.

Right now there's no easy way to experiment this through a compiler
flag, and the only way to experiment this is to change the tablegen
default number of stage to 3. I plan to expose it properly in the next
PR.

IREE: Intermediate Representation Execution Environment

IREE (Intermediate Representation Execution Environment, pronounced as “eerie”) is an MLIR-based end-to-end compiler and runtime that lowers Machine Learning (ML) models to a unified IR that scales up to meet the needs of the datacenter and down to satisfy the constraints and special considerations of mobile and edge deployments.

See our website for project details, user guides, and instructions on building from source.
