feat(gamemode): Add support for new GPU cards via nv_per_profile_editable in gamemode.ini

- Added a new configuration variable `nv_per_profile_editable` to the `gamemode.ini` file.
  - If set to 1 (default behavior), the code will use per-profile offset behavior.
  - If set to 0, the code will use the AllPerformanceLevels API, which is compatible with newer cards like the GTX5060ti.

- Updated the `gpuclockctl` utility to accept the `nv_per_profile_editable` parameter.
  - If the parameter is not provided, it defaults to 1 and uses the previous API for backward compatibility.

This change allows `gamemode` to support a wider range of GPU cards by providing flexibility in how GPU performance levels are managed.

**Notes:**
- Ensure that the `gamemode.ini` file includes the new `nv_per_profile_editable` setting.
- Verify that the updated `gpuclockctl` utility functions as expected with both default and specified values for `nv_per_profile_editable`.

Tested on: RTX 5060 ti (driver 575.64.05) on Ubuntu 25.04
