Remove FramePop trace listener if no outstanding events

Previously we would leave the JvmtiMethodTraceListener installed
forever if we even had a FramePop event requested. This was to prevent
any possible UAF issues with shadow-frames. This changes it so we will
check if there are any outstanding shadow-frames when the event is
disabled. If there are not any left we will remove it and remove the
deopts. This should improve performance after a frame-pop event is
used.
