Fix Windows ARM64 platform signature for Spotify Access Point

Modern Spotify Access Point rejects the obsolete PLATFORM_WINDOWS_CE_ARM signature and CPU_ARM for Windows with ErrorCode::PremiumAccountRequired. Map Windows aarch64 to PLATFORM_WIN32_X86_64 and CpuFamily::CPU_X86_64, resolving connection rejection on Windows on ARM devices.

References #1737 and crmne/spotifast#123.
