A function that would tell me in a platform independent way the pixel
offset of the frame's root window from the top edge of the frame's
"client rectangle" (sorry for the Windows parlance).

I can calculate the remaining pixel edges of the frame's root window by
subtracting the frame's interior pixel width around it.  The minibuffer
window has either what frame-char-height tells me or gets me its pixel
height exactly when called by resize_mini_window.  So the upper part is
the only missing one (modulo the fringe/scrollbar tribulations mentioned
elsewhere).
