quadlet: add support for multiple quadlets in a single file

Browse Source 
Enable installing multiple quadlets from one file using '---' delimiters.
Each section requires '# FileName=<name>' comment for custom naming.
Single quadlet files remain unchanged for backward compatibility.

@@ -16,6 +16,8 @@ This command allows you to:
* Specify a directory containing multiple Quadlet files and other non-Quadlet files for installation ( example a config file for a quadlet container ).
* Install multiple Quadlets from a single file with `.quadlets` extension where each Quadlet is separated by a `---` delimiter. When using multiple quadlets in a single file, each quadlet section must include a `# FileName=<name>` comment to specify the name for that quadlet.
Note: If a quadlet is part of an application, removing that specific quadlet will remove the entire application. When a quadlet is installed from a directory, all files installed from that directory—including both quadlet and non-quadlet files—are considered part of a single application.
Note: In case user wants to install Quadlet application then first path should be the path to application directory.

Note: Multi-quadlet functionality requires the `.quadlets` file extension. Files with other extensions will only be processed as single quadlets or asset files.
