Add support to enable Varbase Media Header on Taxonomy Terms entity type

Problem/Motivation

We can add the media header only on contents types, so when I tried to add a media header on the term page I couldn't do it, so I handled to add a media header on the term page

Steps to reproduce

No fields will be added to the taxonomy, if we add the field manually we will need to include the template and block manually

Proposed resolution

• Add a new entity option, which is a Taxonomy term, with a node entity with some enhancement.
  

            // Planed for allowed entity types to have node, taxonomy.
            // more other entity types if needed.
            $allowed_entity_types = ['node', 'taxonomy_term'];
       

• Refine the code logic for constructing the block by ensuring a more organized order.
• Implement efficient block cache context and logic management.
• Group bundles for supported entity types to improve code structure and maintainability.
• Import managed Entity Type configs for supported entity types. Only when needed.

As a test Example:
The varbase_media_header.settings.yml schema and configs looks as the following when enabled for page, varbase_blog content types and blog_categories terms:

varbase_media_header_settings:
  node:
    page: page
    varbase_blog: varbase_blog
    landing_page_lb: 0
    varbase_heroslider_media: 0
  taxonomy_term:
    blog_categories: blog_categories
    tags: 0
hide_breadcrumbs: false

That is covered with the same config schema
