Clean up map.c /map.h (mono/mono#16746)

* [Mono.Posix] Move Mono_Posix_{From,To}MremapFlags() to support/sys-mman.c

Since mono/mono@b522eab5ff5466debaacf9e971e26cfc464ebba5 Mono_Posix_FromMremapFlags()
and Mono_Posix_ToMremapFlags() contain manual changes for NetBSD. Move the
functions from support/map.c to support/sys-mman.c so that they won't be
overwritten when create-native-map is rerun.

* [Mono.Posix] Fix prototypes in support/stdio.c

In mono/mono@ed892ccf27849c082ce6ca46fa8b96d86ca7c329 wrapper functions for several
stdio functions were added, but the prototypes in map.h were manually
written, not using create-native-map. This commit changes the prototypes so
that they match the output of create-native-map.

* [Mono.Posix] Undefine HAVE_STRUCT_SOCKADDR_IN6 in support/map.c on MSVC

In mono/mono@22b6b9581418260397b701c17b16c3eb55136de7 a manual change to support/map.c
was added to prevent Mono_Posix_FromSockaddrIn6() and
Mono_Posix_ToSockaddrIn6() from being built for windows even if
HAVE_STRUCT_SOCKADDR_IN6 is defined. Instead undefine it in a header file
to avoid manual changes to map.c.

With this commit map.c, map.h and NativeConvert.generated.cs contain no
manual changes anymore.
