feat: add set_dock_visibility method

[1111mp]

Add set_dock_visibility method to support setting the visibility of the application in the dock.

With the upstream PR(tauri-apps/tao#1058) merged, I think it's time for tauri to support it. Even though we already have set_activation_policy. Here’s the difference from ChatGPT about how they are implemented:

Detailed Comparison

TransformProcessType(set_dock_visibility):

• Functionality: Used to change the process type, such as making an application a UI element, which does not show up in the Dock.
• Flexibility: Allows dynamic state changes of the application, suitable for apps needing runtime display adjustments.
• Complexity: Requires handling more details and potential system errors, especially during rapid state transitions.
• Use Case: Suitable for applications needing to hide or show the Dock icon under specific conditions, like background tools.

NSApplicationActivationPolicy:

• Functionality: Controls the application's Dock display and menu bar presence by setting the activation policy.
• Simplicity: Directly sets the activation policy, straightforward and easy to implement.
• Safety: Fewer risks of system errors, suitable for most applications.
• Use Case: Suitable for applications that do not require frequent dynamic changes to Dock display status.

Comparison Table

Feature/Functionality	TransformProcessType	NSApplicationActivationPolicy
Control Method	Controls by changing process type	Controls by setting application activation policy
Flexibility	High: Can dynamically change application state	Low: Typically set at application launch, not easily dynamic
Implementation Complexity	High: Requires handling process transformation details and potential issues	Low: Simple to set, easy to implement
Error Risk	High: Potential system errors with rapid state changes (e.g., multiple Dock icons)	Low: Generally safe and reliable
Applicable Scenarios	Apps needing dynamic Dock icon visibility	Standard applications needing simple Dock visibility control
Usage Examples	Background tools, auxiliary applications	Standard applications like text editors, browsers, etc

This comparison shows that TransformProcessType offers higher flexibility but comes with increased complexity and error risk, whereas NSApplicationActivationPolicy provides a simpler, safer way to control an application's Dock visibility. The choice between the two should be based on the specific needs of the application.
