Add file-existence guards around firmware and OVMF download
calls in integration test scripts that were missing them.
Also guard prepare_linux() in test-util.sh so it returns
early when the kernel binary is already present.
This lets users pre-populate the workloads directory (e.g.
via CH_CUSTOM_KERNEL, CH_CUSTOM_FIRMWARE, CH_CUSTOM_OVMF)
and avoid redundant network fetches or source builds inside
the container.
Updated scripts:
- test-util.sh (prepare_linux early return)
- run_integration_tests_aarch64.sh
- run_integration_tests_vfio.sh
- run_integration_tests_windows_x86_64.sh
- run_integration_tests_windows_aarch64.sh

Add an `iommufd` flag to existing VFIO integration tests. When false,
tests use the legacy vfio container/group backend (existing behavior).
When true, tests use vfio cdev with iommufd and vfio_p2p_dma=off.
vfio_p2p_dma=off is required because the VFIO test runner uses a stock
Ubuntu 24.04 kernel (v6.8) which does not support mapping device MMIO
pages (VM_PFNMAP) through iommufd, causing IOMMU_IOAS_MAP to fail with
-EFAULT on MMIO BAR regions.

It is a common use case to run a subset of tests locally to verify
certain functionalities.
The default behaviour for nextest is to error out if no tests are run.
That causes the test scripts to return a non-zero value (failure). Pass
`--no-tests=pass` to nextest to match what `cargo test` does if no tests
are run.

TL;DR: Massive quality of life improvement for devs
Cloud Hypervisor uses the Cargo test framework for multiple tests:
- normal unit tests
- unit tests requiring special environment (the Tap device tests)
- integration tests requiring a special environment
This prevented the execution of `cargo test --workspace`, which results
in a very poor developer experience. Although
`./scripts/run_unit_tests.sh` exists, there are valid reasons why devs
cannot or even don't want to use it.
By adding a new `chv_testenv` rustc config, we can conditionally only
activate tests when the `./scripts/` magic runs them. This improves
the general developer experience by a lot.

The script "run_integration_tests_vfio.sh" requires to be ran on a
specific machine with specific hardware (e.g. the "vfio" bera-metal
worker equipped with a Nvidia Tesla T4 card). So the provisioning of the
running machine is out of the scope of this script, including the custom
guest image with Nvidia drivers installed, and properly configured
Nvidia Tesla T4 card.

There is no need to reconstruct it from within the scripts since the
main script already constructed it once.
Drop the previously useless setting of BUILD_TARGET from various

Re-enable the VFIO integration now the machine is back online.
The image has been updated to rely on Ubuntu 22.04 (Jammy) and it's
smaller given only the NVIDIA drivers along with the nvidia-smi tool are
installed.
The test to verify the GPU is functional has been simplified given it
only relies on nvidia-smi to validate it has been able to find the Tesla
T4 card, meaning the associated driver was loaded correctly.

This uncouples it from the features used for building the binary under
test allowing it to use the default build features.
This change also removes the feature control from the test scripts where
it was never used (e.g. run_integration_tests_sgx.sh)
This allows the combined binary to be used for all testing but allows
the disabling of tests known not to work under mshv.

Since it's not possible to run the integration test test_vfio on Azure

The dev container interface script (e.g. 'dev_cli.sh') now supports the
following arguments syntax for running tests:
`tests [--unit|--cargo|--all] [--libc musl|gnu] [-- [<test scripts args>] [-- [<test binary args>]]] `
In this way, we can pass custom arguments to the test binary (either
"cargo test" or "performance-metrics") with our dev container script.
For example:
`$ ./dev_cli.sh tests --metrics -- -- --report-file /tmp/metrics.json --test-filter latency`
`$ ./dev_cli.sh tests --integration -- --test-filter "test_serial" -- --nocapture --test-threads=1`

Relying on guest Ubuntu image 21.04, including a 5.11 kernel, this patch
adds some additional tests to the VFIO baremetal integration tests. It
adds a test for ACPI memory hotplug, another one for virtio-mem memory
hotplug, and finally a test for hotplugging the NVIDIA card.
The existing test already taking care of the reboot has been renamed.
The script running "cargo test" has been modified to run only one thread
at a time, so that each test run sequentially. This is mandatory since
the card can't be shared across multiple VMs.
