scripts: compiler.h: add Windows support
We lack endianness conversion functions for Windows. Import them from
the public-domain portable_endian.h[1]. We skip the 64-bit XBox support
though as it's unlikely we'll need to run imx-usb-loader on that
particular game console.
While at it, only define min when it's undefined. This works around one
of the winapi headers indirectly included defining it.
