[Light Switch] Adding telemetry events

[Jaylyn-Barbee]

Adding events to track the following:

Event Name	Description	Data collected
Microsoft.PowerToys.LightSwitch_EnableLightSwitch	Triggered when Light Switch is enabled or disabled.	Whether the module is enabled or disabled (bool)
Microsoft.PowerToys.LightSwitch_ShortcutInvoked	Occurs when the shortcut for Light Switch is invoked.
Microsoft.PowerToys.LightSwitch_ScheduleModeToggled	Occurs when a new schedule mode is selected for Light Switch.	The new mode selected (string)
Microsoft.PowerToys.LightSwitch_ThemeTargetChanged	Occurs when the options for targeting the system or apps is updated.	The new options selected (two bools)

The above events that are related to Light Switch settings are tracked in the "LoadSettings" function inside the service but only if the value has changed. The Enabled event as well as the Shortcut event are tracked in the module interface.

Pull request overview

This PR adds comprehensive telemetry tracking to the Light Switch module to monitor user engagement with various features. The implementation follows PowerToys' telemetry patterns using TraceBase and TraceLoggingWriteWrapper, ensuring events respect privacy settings. Telemetry events are triggered only when settings change or when users invoke actions.

Key changes:

• Added new telemetry infrastructure in LightSwitchService with trace.h/trace.cpp files
• Integrated telemetry calls in LoadSettings to track schedule mode and theme target changes
• Added telemetry in module interface to track enable/disable state and shortcut invocations
• Updated DATA_AND_PRIVACY.md with Light Switch telemetry event documentation

You could use Telemetry Real-Time Tool to verify the event actually fires and the schema is expected, and after that done, I can approve this

Looks good, make sure these events can be found in the windows telemetry
