Pull request overview

This pull request implements component separation for RDKEMW-11639 by externalizing middleware and platform-related code from AAMP. It introduces a new build option (CMAKE_EXTERNAL_PLAYER_INTERFACE_DEPENDENCIES) that allows using player interface components from an external repository instead of the built-in middleware.

Changes:

• Adds installation script for external middleware-player-interface components with pkg-config generation
• Modifies CMake build system to support conditional compilation with external vs internal middleware dependencies
• Improves test robustness with better null handling and symbol visibility controls to prevent GLib/GStreamer clashes

Hardcoding the git branch 'feature/RDKEMW-11639' in the installation script makes this non-reusable and will break once this feature branch is merged or deleted. The script should either use a stable branch name (like 'main' or 'master') or make the branch name configurable through an environment variable or parameter.
