Enable native support for Windows on arm64
This PR will enable cross-compilation of Bazel binaries for win/arm64 from win/x64
`bazel build -c opt --cpu=x64_arm64_windows //src:bazel.exe`
Generated bazel executable can be used for native compilation in win/arm64
`bazel.exe build //main:hello-world`
Following changes are included
- Add win/arm64 JDK 17
- Fix AutoCpuConverter.java to identify win/arm64 CPU
- Extend build_bazel_binaries.yml to cross-compile for win/arm64
- Fix msvc toolchain to look for tools in HostX86 directory as well
- add clang-cl support for windows/arm64 host
- Extend host_windows config to handle windows x64 and arm64 hosts.
Closes #14340.
