session-lock: send locked after the lock screen is properly rendered (#6850)

Browse source 
The protocol says:
> The locked event "must not be sent until a new "locked" frame (either from a
> session lock surface or the compositor blanking the output) has been presented
> on all outputs and no security sensitive normal/unlocked content is possibly
> visible".

This helps users ensure the screen is properly locked before suspending
the machine. (e.g. with swaylock --ready-fd)
