Add "Header" Option to JsExternal SPA Library Plugin and add ability to set unlimited and arbitrary attributes on external script tags [#3557794]

Problem/Motivation

We need a new “header” option in the SPA library plugin configuration that allows external JavaScript libraries to be optionally loaded in the document header instead of the footer. This provides more flexibility in cases where scripts need to be loaded early.

Title:

Add "Header" Option to JsExternal SPA Library Plugin

» Add ability to set unlimited and arbitrary attributes on external script tags

We also need the ability to attach an external script with any number of custom attributes. Currently, the implementation only supports a predefined or limited set of attributes. For our use case, external scripts must be configurable with arbitrary attributes (e.g., data-*, custom flags, or integration-specific parameters).
