[PATCH 1/2] gpu: nova-core: add a KUnit test configuration option

[Yury Norov <ynorov@nvidia.com>]

The continuation-record KUnit tests are currently built whenever both
Nova Core and KUnit are enabled, providing no way to select the tests
independently.

Add CONFIG_NOVA_CORE_KUNIT_TEST and use it to guard the test suite.
Follow the usual KUnit convention of enabling the option through
CONFIG_KUNIT_ALL_TESTS.
