Consolidate templates for Fiori elements FPM

[tobiasqueck]

The goal is to provide templates for adding custom extensions to a Fiori elements for OData v4 application that can be used in the SAP Fiori tools (in guided development as well as page modeler) that follow the guidelines provided in the Fiori elements flexible programming model explorer at https://ui5.sap.com/test-resources/sap/fe/core/fpmExplorer/index.html#/customElements/customElementsOverview

The current state is a draft implementation to get a better understanding what is needed for #73

@nlunets I noticed that in the FPM explorer you add custom pages as components to a Fiori elements application, however, when using the page modeler in the SAP Fiori tools, custom pages are added as views.
Both work technically but what would be your recommendation?

@Klaus-Keller FYI

[nlunets]

The recommendation would be to add them as components as this enables the usage of building blocks inside the custom page :)

[nlunets]

Overall it looks good (simple but good).
I'm wondering if we should add more details / options (like how to extend controller extensions and the like in the controller)
Small comments to change

[Klaus-Keller]

@nlunets, what is the minimum UI5 version this template can be used?

[nlunets]

I would say 1.93

I would say 1.93

@nlunets
is it regarding component or controller approach? In tool-suite we have two templates using controller approach:

1. For versions above 1.88 with sap/fe/core/PageController
2. For versions below 1.88 with sap/ui/core/mvc/Controller instead of sap/fe/core/PageController

Main explanation was that sap/fe/core/PageController is available since 1.88 - https://sapui5.hana.ondemand.com/#/api/sap.fe.core.PageController

OK for me, but a merge from main seems to be required

[tobiasqueck]

Before merging, I would need an approval for each of the following aspects

• Integration into SAP Fiori tools application modeller (@stefanschreck @zdravko-georgiev)
• correctness for generated elements (@nlunets @stefan0816 )
• standards and requirements for code in open-ux-tools (@devinea @ullasholla )

[nlunets]
