ci: Use 7z format for Windows build artifacts

This commit updates the CI workflow to output .7z archives for the
Windows build artifacts.

The 7z format uses the LZMA compression algorithm, which offers
significantly improved data compression ratio.

The `-l` option is used such that symbolic links are stored as copies
of the linked files because Windows requires administrator privileges
to create symbolic links.

Note that 7z performs multi-threaded compression by default.

For more details, refer to the issue zephyrproject-rtos#567.
