[RFC V3 PATCH 00/13] Support ACPI Control Method Sleep button

[Annie Li <annie.li@oracle.com>]

The ACPI sleep button can be implemented as a fixed hardware button
or Control Method Sleep button.

The patch of implementing a fixed hardware sleep button was posted
here 1). More discussions can be found here 2). Essentially, the
discussion mainly focuses on whether the sleep button is implemented
as a fixed hardware button or Control Method Sleep button. The latter
benefits various architectures since the code can be shared among
them.

This patch set implements Control Method Sleep button for both x86
and Microvm.(The V1 patch set was posted previously here 3). We
rebase all the patches on QEMU9.1.0 and re-post V2 here 4). This V3
patch set here is rebased on QEMU 10.0.0-rc3. The sleep button support
for MicroVM is added, however, its support for ARM platform in V2 is
removed due to lower interests of it and more efforts in the firmware.

For x86, a sleep button GPE event handler is implemented, so a GPE
event is triggered to indicate the OSPM the sleep button is pressed.
Tests have been done for Linux guest, and Windows Server guest,
this sleep button works as expected.

For MicroVM, a GED event is triggered to notify the OSPM. This GED
event is also applicable for ARM platform, but this V3 patch set
doesn't cover ARM platform as what V2 did 4). Tests have been done
for Linux MicroVM guests.

System_wakeup doesn't work for MicroVM for now due to the missing
support of it. This patch set only covers system_sleep, not the
wakeup part.
