RTLA updates for v7.3

Browse source 
- Extend support for unsetting CLI options
 
   libsubcmd auto-generates "--no-<option>" to unset options, provided
   the option callback supports it. Implement this for RTLA CLI beyond
   boolean options, and document the few exceptions that are left out.
 
 - Test all tracer options in runtime tests
 
   Verify that RTLA sets osnoise/timerlat options correctly by reading them
   from tracefs during runtime tests.
 
 - Improve range validation for option arguments
 
   Make CLI range validation consistent with the kernel limits and unify
   implementation and error messages between options.
 
 - Improve invalid option argument parsing
 
   Consistently reject invalid values for numeric option arguments with
   a unified error message for all options.
