refactor: is_kernel_option_enabled (#267)

Current "is_kernel_option_enabled" function is doing many things, like checking for a kernel option AND checking a kernel module state AND checking if it is disabled
We split it in different functions:
        - is_kernel_monolithic
        - is_kernel_option_enabled -> check for a kernel configuration in the running kernel
        - is_kernel_module_loaded -> check if a module is currently loaded
        - is_kernel_module_available -> check if a module is configured in all available kernel configs
        - is_kernel_module_disabled   -> check if a kernel module is disabled in the modprobe configuration

Also:

- update its behaviour to debian 12 CIS recommendation, to check if a module is "available in ANY installed kernel"
- fix "disable_usb_storage" to look for correct module name once loaded : issue #249
- the associated checks now check separately if the module is loaded, and if it is configured
- for checks about kernel module presence, the "apply" function now manages to disable the module in the modprobe configuration (if kernel not monolithic) (but still wont unload it)
