  rtla/cli: Unify and improve handling of invalid option arguments (2026-08-05 10:14:40 +0200)

----------------------------------------------------------------
RTLA patches for 7.3

- 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.
