ACPICA: OSL: Add configurability for error message functions.

This patch extends ACPI_HW_DEPENDENT_x mechanism to all error message related functions so that the OSPMs can have full control to configure them into stub functions. This patch doesn't include code for Linux to use this new mechanism, thus no functional change. Lv Zheng.
