Handle Bug#24526 without breaking Emacs on tiling WMs (Bug#48268)

Since tiling window managers may react allergically to resize
requests immediately following MapNotify events on X, make sure
that such requests are issued only when a new frame should not
become visible and a size has been explicitly requested for it.

* lisp/faces.el (x-create-frame-with-faces): Mark frame as
'was-invisible' if it should be initially invisible or iconified
and has its size specified explicitly.
* src/frame.c (make_frame): Initialize new frame's was_invisible
flag.
(Fframe__set_was_invisible): New internal function.
* src/frame.h (struct frame): Specify size of new_size_p slot.
New flag was_invisible.
* src/w32fns.c (Fx_create_frame)
* src/nsfns.m (Fx_create_frame)
* src/xfns.c (Fx_create_frame): Set new frame's was_invisible
flag.
* src/xterm.c (handle_one_xevent): Call xg_frame_set_char_size
after a PropertyNotify or MapNotify event only if F's
was_invisible flag was set.
