GPU Kernel Function Attributes Module

This module provides structures for defining and managing GPU kernel function attributes. It implements functionality similar to CUDA's CUfunction_attribute enum, allowing for querying and setting various attributes that control kernel execution behavior and resource allocation.

The module includes:

• Attribute: A value type representing different GPU kernel function attribute types
• FuncAttribute: A structure that pairs an attribute type with its value

These structures enable fine-grained control over GPU kernel execution parameters such as shared memory allocation, cache behavior, and cluster configuration.
