[crodriguesbr]

Description

Remove linux-arm64 build target from the release workflow to simplify the CI/CD pipeline.

• Remove linux-arm64 from build matrix
• Remove cross-compilation toolchain installation step
• Simplify release to 4 platforms: linux-x64, win-x64, osx-x64, osx-arm64

Motivation and Context

Cross-compilation for Linux ARM64 requires additional toolchain setup and increases build complexity. Removing this target simplifies the release workflow while still supporting the most common platforms.
