ACPICA: Events: Reduce source code difference for the ACPI_EVENT_FLAG_HANDLE renaming.

This patch is partial linuxized result of the following ACPICA commit:
ACPICA commit: a73b66c6aa1846d055bb6390d9c9b9902f7d804d
Subject: Add "has handler" flag to event/gpe status interfaces.
This change adds a new flag, ACPI_EVENT_FLAGS_HAS_HANDLER to the
acpi_get_event_status and acpi_get_gpe_status external interfaces. It
is set if the event/gpe currently has a handler associated with it.
This patch contains the code to rename ACPI_EVENT_FLAG_HANDLE to
ACPI_EVENT_FLAG_HAS_HANDLER, and the corresponding updates of its usages.
