feat: improve keyboard accessibility navigation

[United600]

• Add more access keys
• Improve the SplitButton behavior (Tooltips and AutomationProperties)
• Add NavigationView keyboard behavior (Improves the keyboard interaction on the built-in buttons)
• Disable PaneAutoSuggestButton IsTextScaleFactorEnabled
• Add localization support for access keys
• Add Search shortcut

Checklist

• [ ] On fullscreen, pressing the Alt key should toggle the PlayerControls visibility
• [ ] Sliders exhibit focus trapping
• [ ] KeyTip placement for the AutoSuggestBox can be inconsistent after the flyout is opened
• [ ] Support KeyboarAccelerators localization

Probably should add some documentation, or improve the resource comments clarity (as concisely as possible), to help the localization efforts. Maybe adding links to this page section or this section.
