Hide toggle to Turn on Wi-Fi automatically preference in Search settings

- If the location setting is enabled, keep the current design. that the user can switch the toggle directly in the search settings to the "Turn on Wi-Fi automatically" toggle preference.

- If the location setting is disabled, hide the switch toggle to "Turn on Wi-Fi automatically" preference to avoid unexpected behavior.

- The user can click the "Turn on Wi-Fi automatically" preference to jump to the Network preference settings, and see a reminder message in the summary to enable the location settings first before switching the toggle.

- Move the check for mFragment to a suitable location to avoid unnecessary checks.
