virtiofs: add support for statx syscall

[benhillis]

This change updates the WSL devicehost nuget package to the latest version which supports the statx syscall. For more context see microsoft/openvmm#2589

I've also added a test that fails before the new devicehost package and passes afterwards.

Pull request overview

This pull request updates the WSL DeviceHost NuGet package to version 1.1.10-0, which adds support for the statx syscall in virtiofs. The update enables previously skipped tests to run on virtiofs filesystems while adding more granular test skips for operations that still don't work.

Changes:

• Updated Microsoft.WSL.DeviceHost package from version 1.1.8-0 to 1.1.10-0
• Removed virtiofs test skip for DrvFsTestDeleteCurrentWorkingDirectory as it now works with statx support
• Added targeted virtiofs skip for chdir("..") operation from a deleted directory that still doesn't work on virtiofs
