Subject: [PATCH] Export stable Azmq::libzmq target

Create INTERFACE IMPORTED target instead of aliasing PkgConfig::LIBZMQ
to avoid exporting pkg-config targets in azmq's exported configuration.

When azmq creates an ALIAS to PkgConfig::LIBZMQ, the pkg-config target
gets included in azmq's exported CMake config, causing downstream builds
to fail when pkg-config results differ between environments.

This patch copies the properties from PkgConfig::LIBZMQ into a new
INTERFACE IMPORTED target to break the dependency on pkg-config in
the exported configuration.

The implementation includes null checks for robustness and copies all
relevant INTERFACE_* properties including link libraries, include
directories, compile options, compile definitions, and link options.
