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.

After updating the Linux kernel to 6.19.6 the second segment (segment=1)
is now under the 2nd IOMMU group (which it a more logical setup) and as
such the added device which is on that segment is in that second IOMMU
group.
The same check is made in test_vdpa_block so also test there.

The ivshmem tests involving snapshot/restore & live migration are
failing in the MSHV CI with this error:
Could not get vCPU state GetMsrEntries(
Hypercall 80 failed with 0x5 : InvalidParameter ...<snip>)
This needs more investigation. It is worth noting that the general live
migration tests are also not run in the CI for MSHV.
Disable these tests for MSHV for the time being.

[1]. As a result, few changes are made to our integration tests and test

Allow tap interfaces to be configured with an IPv6 address. The change
is fairly straightforward: we need to update the API types and CLI
parsing to accept either an IPv6 or IPv4 and then match on the IP
address type when the tap device is configured.
For IPv6 addresses, the netmask (prefix) must be provided at the same
time as the address itself (in the SIOCSIFADDR ioctl). They cannot be
configured separately. So we remove the separate "set_netmask" function
and convert "set_ip_addr" to also accept a netmask. For IPv4 addresses,
the IP address and netmask were already always set together, so this
should have no functional impact for users of IPv4 addresses.

The new locking behavior uncovered that unfortunate test situation:
Many tests running in parallel access the same disk image with
rw permissions. Luckily, none of the tests actually writes to
the disk. Therefore, we can set it to readonly=true. In case this
changes, the test needs to be moved to the sequential test module.

Asserting on .is_ok()/.is_err() leads to hard to debug failures (as if
the test fails, it will only say "assertion failed: false". We replace
these with `.unwrap()`, which also prints the exact error variant that
was unexpectedly encountered (we can to this these days thanks to
efforts to implement Display and Debug for our error types). If the
assert!((...).is_ok()) was followed by an .unwrap() anyway, we just drop
the assert.
Inspired by and quoted from @roypat.
