Adding a WindowManagerProvider and WindowManagerUtils to provide the required WindowManager instance based on the status of ViewCapture tracing being enabled or disabled in SysUI.

Use WindowManagerProvider in case a WindowManager instance needs to be
created from a custom context.
Use WindowManagerUtils only in classes which are not part of a dagger
graph.
