Clean up VtsHalRadioTargetTest

Refactor class design so RadioServiceTest extends TestWithParam and
each individual radio service test extends RadioServiceTest.
Move setup and teardown logic common to all classes to RadioServiceTest.
Add logs to print when each test starts/finishes to help debug issues.
Remove unused imports and fix some typos.
Change unique_lock to lock_guard in notify to prevent MTE errors.
