[RONs] Fix ToplineView and LargeIcon Overlapping

NotificationToplineView content overlaps with largeIcon since large icon size is static and it doesnt show the actual size of the icon, which is calculated in Notification.java(`#setRightIconState`)
This CL uses the large icon size which is set in Notification.java

Fixes: 406483321
Flag: android.app.ui_rich_ongoing
Test: Post a progressstyle RON with Ride Share largeIcon. ToplineView and largeIcon shouldn't overlap
