ci: Windows arm64 packages #35345

Problem:
Neovim binaries are not provided for Windows ARM64.
GitHub Actions now offer native CI runners for Windows on ARM devices
(windows-11-arm), enabling automated builds and testing.

Solution:
- Modified CMake packaging to include packaging windows on arm binaries.
- Modified env script to install and initialize vs setup for arm64 arch.
