Summary [Win] Cross-compile ARM64 from Linux

Enable building the Windows port from ARM64 Linux. We'll likely need to drop the Wine requirement - Wine on ARM64 Linux is difficult to install and not as well baked as x64. To do that we'd need to build the host tools when cross-compiling + use those, instead of building the Windows tools and running them via Wine. Most of the changes will be in WebKitRequirements - remove Wine requirement from ICU, and fixing bugs around arm64_neon.h (MSVC specific) vs arm_neon.h in libwebp / zlib-ng. These are dependencies that aren't present on JSC-only so Bun hasn't hit them yet. Follow-on from bug282276
