bug#23369: 25.0.93; CANNOT_DUMP build fails if resizing terminal during startup in tty mode

[Glenn Morris]

I found this easy to reproduce but hard to debug, but it seems like
making window.el's internal--before-save-selected-window check
(featurep 'frame) before it tries to call frames-on-display-list
fixes it for me.
