Set maximum number of threads in the thread block for CUDA target

PTX programming models provides some performance tuning directives; see https://docs.nvidia.com/cuda/parallel-thread-execution/index.html#performance-tuning-directives The downstream compiler namely ptxas leverages these information for better register allocation or to handle other resource management that improves the performance.

As far as I understand, iree knows the number of threads for thread blocks. This PR sets `maxntid`.

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.

Project Status

IREE is still in its early phase. We have settled down on the overarching infrastructure and are actively improving various software components as well as project logistics. It is still quite far from ready for everyday use and is made available without any support at the moment. With that said, we welcome any kind of feedback on any communication channels!
