Wire up GPE eventfd forwarding and crosvm's GPE emulation.
This patch allows to provide ACPIPMResource with the list of GPEs
which should work as direct physical (passthrough) GPEs rather than
purely emulated ones.

In order to allow handling physical GPE in the guest, implement
physical SCI interrupts forwarding from the host to the guest.
It uses an eventfd based mechanism similar to how we normaly do
forwarding of other level-triggered interrupts. The difference is that
SCI trigger events from kernel are not injected directly to irqchip.
In order to support injecting both physical and virtual SCI interrupts
(so that some GPEs can be handled as physical while other GPEs can be
emulated), SCI trigger event is intercepted by ACPIPMResource which
injects it to irqchip via another eventfd - the same eventfd which is
used for injecting virtual SCI interrupts.
Similarly, resample event for physical forwarded SCI is received
via the same eventfd as for virtual SCI, then forwarded back to kernel.

Based on the previous proposal in [1].
* The Executor is now completely platform-agnostic and only relies on
the platform to provide a type that implements the `PlatformState`
trait.
* The crate provides concrete high-level types rather than forcing users
to deal with trait objects and async-trait. Currently, only File and
Event are supported. Support for timers, sockets, and pipes will be
added in subsequent changes.
* Each high-level type delegates the implementation to a
platform-specific type and exists mainly as a place to hold
documentation and tests.
* On Unix the io_driver module provides async versions of various
IO-related syscalls, which are used by the platform-specific File and
Event types to implement the required behavior.
* io-uring support can be disabled at compile time. When uring support
is enabled, we make a runtime check to decide whether or not to use
it. The actual io-uring driver is currently unimplemented and will be
added in a subsequent change.
One non-trivial downside of this change is that the futures returned by
the various async methods are !Send and !Sync, which means that they can
only be awaited from the same thread on which they were started. In
practice this should be fine since current crosvm (and Chrome OS) code
doesn't really make use of sending futures to different threads. This
can also be mitigated by using `Executor::spawn_local` and a
`oneshot::channel` to isolate the !Send future from the outer async
fn (as long as the output of the future is Send). See the crate
documentation and the `outer_future_is_send` test in `src/executor.rs`
for more details.

The new runner makes use of the simplified crosvm build and greatly

The new test runner also makes use of the new testvm tools to make it

See ./tools/run_tests --help for usage instructions.
To allow more iterative testing with the same test targets, this CL

to build for the target arch and run on the test target.

The syscall_defines crate is redundant with an up to date libc. This
change removes any dependency on syscall_defines. A new libc is required
to bring in some new syscall numbers like the ones for io_uring.

This patch adds support for creating udmabufs via a guest provided
sg-list. Ideally, we'd create the udmabuf from a virtio-gpu guest
dedicated heap, but that needs further investigation.
In terms of the protocol, these following prototype items are added:
BLOB_CREATE_GUEST_HANDLE: "create an udmabuf" or an OS-specific
equivalent. This can be used with the guest dedicated heap or system
memory. Right now, only system memory is used.
We also want to associate the udmabuf with any host side metadata. For
example, SET_SCANOUT_BLOB doesn't passthrough the modifiers since
virtio-gpu KMS + modifiers is annoying. Simple solution: just ask the
host for the modifier. This could also enable different caching types
if the guest blob is mappable (for example, the MSM GPU driver currently
only supports WC mappings. We might also want cached mappings for
camera).
Incidentals:
* Add a placeholder for RESOURCE_SYNC
