feat(native): Custom Loader

[skuzzis]

This pull request updates the build workflow to add support for building and packaging the swiftlys2-loader plugin for both Linux and Windows platforms. It introduces new jobs to build the loader, updates the packaging process to include loader artifacts, and ensures that the loader and its related debug symbols are incorporated into the final release packages.

Build and packaging workflow improvements:

• Added new linux_loader and windows_loader jobs to the GitHub Actions workflow to build the swiftlys2-loader plugin for Linux and Windows, respectively, using the appropriate build environments and tools.
• Updated the dependencies for the packaging job to ensure that loader builds are completed before packaging starts.
• Modified the packaging steps to download and include the loader plugin artifacts and their debug symbol files (pdb) for both Linux and Windows in the release packages.
• Updated the packaging script to copy the loader files and debug symbols into the correct directories within the final Linux and Windows release folders.
