Launch/Bring to the foreground Content App on Target Navigator and Co…

…ntent Launch Command (#34223) * Launch content app on command [Problem] 3P content app does not have permissions to launch itself and put main activity in foreground. This is necessary in response to ContentLauncher and TargetNavigator cluster commands. [Solution] Intercept the LaunchContent and NavigateTarget commands in ContentAppEndpointManagerImpl. Then start content app main/launch activity if it's not already in the foreground before sending command intent. [Testing] WIP * Add logic to detect foreground apps * Restyled by whitespace * Restyled by google-java-format * Update code * Restyled by google-java-format --------- Co-authored-by: Lazar Kovacic <[email protected]> Co-authored-by: Restyled.io <[email protected]>
