[Enhancement] Refine error messaging in LowerBulkCopy for global and shared range checks (tile-ai#599)

* [Enhancement] Improve error messaging for global and shared range legality checks in LowerBulkCopy

- Updated error messages in the LowerBulkCopy function to provide clearer context when global and shared ranges are illegal.
- Enhanced the readability of the error output by including tensor names, improving debugging and validation processes during bulk copy operations.

* [Enhancement] Refine error messaging in LowerBulkCopy for global and shared range checks

- Improved the clarity of error messages in the LowerBulkCopy function by enhancing the output format.
- Included additional context in error messages to aid debugging when global and shared ranges are found to be illegal, ensuring better traceability during bulk copy operations.
