Include Windows header and define NOMINMAX for Windows ARM64 builds

[MugundanMCW]

PR Description:

• The compilation of Embree library failed on Windows ARM64 due to a missing definition of the DWORD type and macro conflicts caused by min and max definitions.
• The build failures occurred because of the omission of <windows.h> before using Windows specific typedefs in sse2neon.h, and the NOMINMAX macro was not defined to suppress min/max macro expansions that conflict with standard C++ functions. This PR adds a guarded include of <windows.h> for Windows ARM64 builds and defines NOMINMAX to prevent the conflicts.
