This commit introduces ACPI0003 emulated device, which can be enabled by
passing "--ac-adapter" argument.
Emulating ac adapter allows to replicate ac adapter state on the guest side.
The host kernel already propagates ac adapter status to user-space by
generating acpi events: acpi_bus_generate_netlink_event so crosvm upon
receiving "ac_adapter" class acpi event, stores the corresponding data
(ac status) into ac register. Next the previously allocated GPE is
triggered to inform the guest about status change.
Guest upon handling GPE, thanks to generated aml code:
Device (ACDC)
{
Name (_HID, "ACPI0003" /* Power Source Device */) // _HID: Hardware ID
OperationRegion (VREG, SystemMemory, 0x0000000220E00010, 0x10)

triggers Notify on AC adapter and therefore replicates the host
ac_adapter state (accessing ACEX pointed by opregion results with trap
to crosvm, which returns previously stored ac status).

This implements the equivalent logic on crosvm as
UFFD_FEATURE_EVENT_FORK. When each device process forks, the ProxyDevice
creates userfaultfd and send it to the monitor process by
SwapController::on_process_forked().
Crosvm does not have any child processes which may access the guest
memory except device processes as of now. Crosvm forks
virgl_render_server, but the mmap is not preserved in the process on
execve(2) since it is a different binary. Also no device process forks
grandchild processes according to the seccomp policy.
We actually can't use UFFD_FEATURE_EVENT_FORK because the feature does
not support non-root user namespace (go/uffd-fork-user-ns) and ARCVM
runs in a non-root user namespace.
This also adds syscalls to seccomp policies for devices to allow the
processes to create and setup a userfaultfd.

Note for x86_64: `Arch::guest_memory_layout` initializes some global
state so some care is needed when moving it relative to other code. In
this case it is safe because the only code being moved before
`Arch::guest_memory_layout` is `get_default_hypervisor`, which is
currently a constant, and `Kvm::new_with_path`, which just performs an
`open` syscall and wraps it in a `Kvm` struct. Neither depend on the
x86_64 specific global state.

As part of commit cadc84b32a the crosvm
suspend command has been extended to generating sleep button injection
in order to put VM in suspend state. Additionally the crosvm suspend
command completed after the guest entered proper power state.
Nevertheless in some circumstances above implementation caused issues.
E.g. when the guest with pass-through devices entered run-time device
suspension, triggering a subsequent system suspend request fails and
makes VM inaccessible. It is because before entering system suspension,
devices which entered device run-time suspension needs to be resumed.
Therefore in problematic scenario:
- VmRequest::Suspend was triggered and it resulted with blocking till
guest entered proper suspend state
- during VM suspension process some pci config write accesses are made,
which in some cases triggers write_msi_reg-> write_msi_capability->
add_msi_route, which underneath sends VmIrqRequest::AddMsiRoute
request
- above VmIrqRequest::AddMsiRoute request can't be satisfied since
VmRequest::Suspend made the run_control wait loop busy waiting and
preventing further requests to be processed
In order to fix the above issue, instead of busy waiting directly in the
run_control wait loop for suspend notification, spawn a new thread, which
will generate the acpi power button and start busy waiting for a
notification that the VM actually entered suspend state. This allows to
postpone sending response over the control tube indicating that the
'crosvm suspend ...' command completed and in the same time process
other Vm*Requests.
Mentioned postponement of 'crosvm suspend ..' completion is crucial
since the full system suspension needs to be blocked till VM actually
enters proper suspend state.
BUG=b:248462336
TEST=With a setup where some device is pass-through to the VM and
--force-s2idle flag is used: wait till pass-through device enters
run-time suspend state and trigger "crosvm suspend

sure that full system suspension/resumption doesn't make VM inaccessible
anymore.

This commit adds a function into pci device trait, which returns the
aml code to construct virtual acpi method. Two pages mmio are used to
pass acpi parameters and return value, when guest access the first page,
vm exit happens and it is trapped into crosvm, when guest access the
second page, no vm exit happens.

Improve clarity and consistency between the variable and its type, given
that it represents the protected/unprotected state AND whether some
firmware needs to be used. In particular, it isn't the protected VM
itself.
Similarly, rename components.protected_vm for the same reason.
OTOH, keep cmd.protected_vm for --protected-vm as it is dedicated to
making the VM protected and follows the name of the CLI flag.
Note: no functional change intended.

If a vfio-platform device has no mmio regions, it is unexpectedly
destroyed at startup (in particular, its vfio device fd is unexpectedly
closed, so its interrupt forwarding stops working, etc) since in
generate_platform_bus() arced_dev is not added to mmio_bus so there are
no more references to the device. To fix this issue, preserve references
to platform devices also in platform_devices field of RunnableLinuxVm.

Previously, the IRQ allocation logic could allocate different IRQ
numbers for the same pin (INTA#/INTB#/...) within the same device. This
would result in conflicting MPTable IRQ source entries where the bus,
device, and pin were the same but the IRQ number was different.
This was not apparent in practice in most cases, since almost all PCI
devices in crosvm support MSI-X, so the pin-based interrupts were not
used. However, the xhci device does not support MSI/MSI-X, so it was
affected when it was allocated one of the conflicting IRQ numbers.
Now that the generate_pci_root code in arch chooses the pin numbers
before assigning IRQs, we can fix this problem by recording previously
used pin to irq mappings within each PCI (bus, device) and reusing them
when appropriate.

Split the IRQ allocation into two PciDevice functions:
1. Ask the device if it has a preferred IRQ (used for PCI passthrough
with VFIO where we want the IRQ and pin assignment to match the
host).
2. Inform the device which IRQ it has been assigned (and providing the
interrupt event object).
This moves the decision of which pin to use into the generate_pci_root
function in arch, which means we will know the pin before assigning an
IRQ. This will be used to ensure that pin <-> IRQ number assignments are
consistent within each device in a following change.
While the API is changing, also take the opportunity to clone the IRQ
event on the caller side so that each individual device does not need to
do it.
