patch 9.1.0028: win32: Ctrl-D cannot be used to close a pipe

Problem: win32: Ctrl-D cannot be used to close a pipe
Solution: Properly detect Ctrl-D when reading from a pipe
(GuyBrush)

Enabling Ctrl-D for gvim pipeline input
and apply defensive programming on account of PR #12752
so that once PR 12752 is merged, CTRL-D will keep on working

closes: #13849
