fix(ci): setup MSVC environment for Windows ARM64 builds

The ring crate build was failing with 'assert.h not found' error because
clang couldn't find the Windows SDK headers. This happens when building
for aarch64-pc-windows-msvc without the proper MSVC environment variables.

This fix adds the ilammy/msvc-dev-cmd action to set up the MSVC developer
command prompt environment (INCLUDE, LIB, LIBPATH, etc.) before building.
The action is configured with 'amd64_arm64' arch for cross-compiling from
x64 to ARM64.
