build: Disable stdcall alias-ing and use kill-at

Disable stdcall aliasing and enable kill-at to ensure our exported
functions don't have the @8, @40, etc suffixes.

This still keeps `--enable-stdcall-fixup` as otherwise the linker can
get confused trying to find exports from the .def. This does not result
in aliases being added, just for them to be found to add to the export
table.

This also switches d3d11 to use the MinGW provided dxgi.lib for linking
and d3d10 to use the MinGW provided d3d11.lib for linking.
Unfortunately the .a's we output seem to still have the @BLAH that we
killed so we cannot use them for internal linkage since using kill-at.

Tested that what we get out of MinGW now is what we want with dllexp.

Supercedes: #3590
