fix(macos): properly handle accessibility permission

[Hazer]

Description

Check for macOS Accessibility permission to allow mouse and keyboard input events to work properly.

• Automatically includes sunshine to the Accessibility list in the Settings pane, no need to find out the binary path;
• Shows prompt to user;
• Logs to the user every time we receive an input event that won't execute because of missing accessibility permission.

Issues Fixed or Closed

• Resolves #2801 for users that haven't added Accessibility permissions.

Needs test coverage on the new methods

[Hazer]

If we are going to test this, this has to be tested only on CI, this cannot be tested on macports test action.

[Hazer]

Waiting for https://github.com/LizardByte/Sunshine/pull/2550 to create the tests

[Hazer]

This needs to be updated and tested on macOS Sequoia before merging.
