[PATCH 0/2] rust: kunit: enforce test configurability

[Yury Norov <ynorov@nvidia.com>]

Make every Rust KUnit test suite require the Kconfig option that controls
it, and let the `kunit_tests` macro apply the corresponding `#[cfg]`
attribute.

Most Rust KUnit suites currently combine a separate `#[cfg]` attribute with
`#[kunit_tests]`. The macro does not enforce this pattern, however, and the
Nova continuation suite currently has no dedicated test option.

Add a Nova Core KUnit option first and use it to guard the existing suite.
Then require a controlling Kconfig symbol in `kunit_tests` by moving the
guard into the macro. Update all callers and documentation as well.
