Fix #10631 New MapStore Home Page

[allyoucanmap]

Description

This PR introduces changes on the plugins related to homepage and resources workflow.
Due to extensive changes the new plugins and related components has been included in a subfolder inside the plugins directory called ResourcesCatalog, here few reason about this structure:

• in development phase used to ensure there was not dependencies with current homepage component
• in general to isolate new components and facilitate the deletion of old one

It would be better if we formalize a way to structure related plugins and shared components, anyway this structure could be changed during the review or later on (eg. when deprecated components will be removed) to align it to the expected structure.

The plugins included and refactored are:

• BrandNavbar: replacement for the OmniBar, this menu will be used in all pages as main menu. OmniBar will be used just for map viewers
• DeleteResource: includes the delete workflow for all the resource category and it will replace all the specific ones
• EditContext: adds buttons to the resource card for contexts
• Footer: refactor of the product Footer plugin, it removes the image and it rely on the html translation for everything
• HomeDescription: refactor of the product HomeDescription plugin
• ResourceDetails: replacement for the resource editing dialog. It will be used both in view and edit mode
• ResourcesFilterForm: a filter form panel available in the home for resources grid
• ResourcesGrid: a resources grid/list view. This plugin replaces all the specific grids with a single one
• Save: includes the save workflow for all the resource category and it will replace all the specific ones
• SaveAs: includes the save as workflow for all the resource category and it will replace all the specific ones
