[codegen] Add max_workgroup_counts to TargetWgpAttr (#17771)

This commit adds a max_workgroup_counts to the workgroup processor
information attribute and sets values for the known targets. Some of
these values may be underestimates as I was not able to locate
information on their values.

This field is added so that we can annotate calls to workgroup.id and
workgroup.count with upper bounds, neabling range inference and strength
reduction.

Note that in some cases (for instance, AMD) we give a
max_workgroup_counts value lower than what is actually supported because
a grid dimension greater than int32_max would be sign-extended to a
negative number to meet the 64-bit nature of `index`.

(This PR is split out of #17707)

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
