in_gpu_metrics: updated config parameters descriptions.

- Sort configuration parameters alphabetically
- Add detailed pattern format info to cards_include and cards_exclude
  (supports '*' for all, comma-separated IDs, and ranges like '0-2')
- Add specific metric names to enable_power and enable_temperature
- Standardize path_sysfs description to 'sysfs mount point'
- Add trailing periods to descriptions for consistency

Fixes #11236.
