ae5118f5c7 Enable windows tests for a few crates
Run tests for sys_util_core, poll_token_derive and balloon_control on
windows.

Using dotfiles to disable/serialize test runs of a subset of crates does
not work well with third party crates as it forces us to commit the dot
file to the crate.

The patch modifies and uses the script that runs linux tests.
This patch also allows us to
- build/test child crate even if parent crate has disabled build/test.
- avoid building crosvm if it is not explicitly specified.

RIP short lived .windows_build_test_skip. You allowed us to run noop
kokoro tests.

Test: py .\tools\impl\test_runner.py --arch x86_64

Benchmark data for vm.Fio.block_stress_rw on my hatch_helios:
 * without uring: read bw = 92047, write bw = 214790
 * with uring: read bw = 114332, write bw = 266586

0108238474 Upstream windows build/test script
The patch also adds files to skip building and testing crates on
windows. When we run
```
tools/windows/build_test.py --skip_file_name .windows_build_test_skip
```

the build/test succeeds without actually doing anything as build/test
for all crates is skipped by creating '.windows_build_test_skip'.

ea956bd908 cros_asyncv2: Add async version of SafeDescriptor
Add a `Descriptor` type that allows callers to asynchronously wait for
the descriptor to become readable or writable.  This is meant to be a
temporary solution so that we slowly convert code over to async rather
than having to do it all at once.

48ee10414c asyncv2: Split fallocate into separate functions
Rather than exposing fallocate directly, add separate functions for each
of the high level operations.  This should make it easier to add
cross-platform support as well as avoid the need to force callers to
deal with libc flags.

7b13ef3ea6 cros_asyncv2: Add crate
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.
