windows: Adjust FD_SETSIZE via commandline define
When using precompiled headers, we cannot pre-define macros for the system
headers from within .c files, as headers are already processed before
the #define in the C file is reached. But we can pre-define using
-DFD_SETSIZE, as long as that's also used when building the precompiled header.
A few files #define FD_SETSIZE 1024 on windows, as the default is only 64. I
am hesitant to change FD_SETSIZE globally on windows, due to
src/backend/port/win32/socket.c using it to size on-stack arrays. Instead add
-DFD_SETSIZE=1024 when building the specific targets needing it.
We likely should move away from using select() in those places, but that's a
larger change.
