* [Enhancement] Implement dynamic unroll factor in CUDA code generation

This commit introduces support for specifying a dynamic unroll factor in the CUDA code generation. The `unroll_factor` map is added to store unroll factors for loop variables, allowing for more flexible and optimized loop unrolling. Additionally, the `unroll` function is integrated into the loop language, enabling users to define unroll factors directly in their code. This enhancement improves performance by allowing tailored unrolling strategies based on specific loop characteristics.

[Enhancement] Improve error handling and assertion messages across runtime and argument binding (#1356)

This commit enhances the error handling mechanisms in the runtime by introducing CPU-safe runtime helpers and refining assertion messages in the CodeGenCHost and ArgBinder. It includes structured packed error messages for various conditions, improving clarity in diagnostics. Additionally, the CMake configuration is updated to always include necessary runtime helpers, ensuring consistent error reporting. The changes aim to provide clearer feedback during runtime errors and improve the overall robustness of the argument binding process.

This commit refines the logic for determining the sign state of indices in the LegalizeNegativeIndex transformation. It prioritizes vector patterns, specifically Ramp and Broadcast nodes, to avoid compile-time lane queries. The handling of scalar indices is also streamlined, ensuring clearer diagnostics when non-negativity cannot be proven. These changes enhance the robustness and clarity of index handling in the transformation pass.

* [Refactor] Improve assertion handling in CodeGenCHost and ArgBinder

This commit refines the assertion message generation in CodeGenCHost by optimizing the handling of equality checks and reducing buffer size for error messages.
