ACPICA: Make acpi_thread_id no longer configurable, always u64
Change definition of acpi_thread_id to always be a u64. This
simplifies the code, especially any printf output. u64 is
the only common data type for all thread_id types across all
operating systems. We now force the OSL to cast the native
thread_id type to u64 before returning the value to ACPICA
(via acpi_os_get_thread_id).
