[PATCH 3/4] tools/power turbostat: Improve --help output

[Zhang Rui <rui.zhang@intel.com>]

Improve the `--help` output of turbostat by standardizing the format
and enhancing readability. The following changes are made to ensure
consistency and clarity in the help message:
1. Use a consistent pattern for each parameter's help message:
   - Display the parameter and its input (if any) on the same line,
     separated by a space.
   - Provide the detailed description on a separate line.
2. Ensure that the first character of each description is in lower-case.

These changes make the help output more uniform and easier to read,
helping users quickly understand the available options and their usage.

No functional change.
