These parameters multiplied the number of type arguments to build_vm
unnecessarily and complicated the thread of execution in the programmers
head. Closures also complicate the borrow rules, making things much
harder to change.
This change uses the results of the closures (e.g. PCI devices, IRQ
chips) as parameters instead. The rest of this change follows naturally
from pulling on that thread until tests pass.
As a result of the removal of several type arguments, the code size was
reduced by ~100KiB on a 5MiB build.

Having a trait for interrupts used by queue and the devices allows for a
slightly different implementation to handle interrupting the guest when
using vhost-user.
Change devices to handle the resample event being optional as it is
handled on the VMM side with vhost_user.

In multi-process mode, we currently rely on dma-buf mmap() to
map GPU buffers into the guest. We usually have to fix the
Mesa driver, and maybe even the kernel to get to work. That's
"kind of" fine for ChromeOS, which owns the entire stack.
For their Virtual Graphics Interface (VGI) initiative, Android
upstream has requested multi-process mode to work in a
cross-platform, generic way. Using Vulkan is the only option
that meets the rigorous, uncompromising, strict, meticulous and
bone-crushing requirements of Android upstream.
This has possible two benefits:
1) We can enable multi-process mode on Nvidia or other
closed-source drivers, which is nice for Cuttlefish.
2) On open-source drivers, dma-buf memory is pinned to the
GTT (amdgpu), even when ideally it can be moved into faster
vram regions. This atleast gives the implementation the
chance to do the smarter and faster option.
We shouldn't run into any SELinux issues since the main crosvm
process is not sandboxed.
Incidentals:
* Changes vulkano_gralloc to consider integrated GPUs and dGPUs.
Metadata query is preferred done on the integrated GPU.
* Update vulkano_gralloc to match top of tree vulkano.

Fds created via dup don't share file descriptor flags with the original
fd, which means that they don't have the FD_CLOEXEC flag set. Use
fcntl(F_DUPFD_CLOEXEC) so that this flag gets set for the duplicated fds
as well.

This CL addresses some minor issues with the existing interface:
1. from_descriptor is too generic for some platforms that require
special handling for file/File backed mappings.
2. Nearly all call sites pass either File or SharedMemory. Now
we just have from_ methods for those types to preserve type
information.
3. Other platforms require additional fields in MemoryMapping, so a
tuple struct no longer makes sense.
4. The mmap syscall error message was misleading as we use it for more
than just the mmap syscall.

WaitContext and Reader/Writer are in the critical path for every device.
Use small vector optimization to avoid making unnecessary small heap
allocations.
The smallvec crate is maintained by the servo authors and only has an
optional dependency on serde.
