[ELF] Define NOMINMAX to fix zlib.h caused build failure on Windows (#70368)

On Windows when zlib is enabled, zlib header introduced some Windows
headers which defines max as a macro. Since OutputSections.cpp uses
std::max with template argument, this causes compilation error.

Define macro NOMINMAX to avoid this.
