Michael Paquier fdd8937c07 Fix huge_pages on Windows 
Since Windows 10 1703, it is additionally necessary to pass a flag
called FILE_MAP_LARGE_PAGES to MapViewOfFile() to enable large pages at
map time.  This flag is ignored on older versions of Windows, where
large pages should still be able to work properly without setting it.
Note that the flag would be set only for binaries that knew about it at
compile-time, which should be more or less all the Windows environments
these days.

Since 495ed0e, Windows 10 is the minimum version of Windows supported by
Postgres, making this change easy to reason about on HEAD.  Per
discussion, no backpatch is done for the moment.
