Tested on silicon

Pull request overview

This PR adds support for AIE4 asynchronous error handling through a new ioctl and corresponding test infrastructure. It extends the existing async error framework to handle AIE4-specific context errors reported by the firmware.

Changes:

• Implements aie4_error_get_last_async() to retrieve cached async errors via ioctl
• Adds AIE4 context error parsing with detailed health report logging
• Introduces TEST_async_error_aie4_io test case using bad_ctrl.elf to trigger and verify context errors
