Make Image Dimensions Configurable

[pykettk]

Description

Add some admin configuration options to control the image dimensions when resizing and provide a fallback (configurable via di.xml) in case of missing dimensions data.

Hello @pykettk,
thanks so much for your contribution, it is greatly appreciated! 🧡 You solved the task that I had the most uncertainty about - retrieving the values from the view.xml files.

I believe your changes are a great foundation to continue development. I have tested it locally and confirmed that this solution works 🙌 There is a little thing that I will highlight in a comment, but I would suggest to proceed as follows:

• I will merge this branch into main
• Based on your changes, I will create a pull request with additional features
  • add a system.xml configuration for the other image types
  • add virtual types to filter out the relevant images in the view.xml (e.g. only showing the images of type thumbnail for setting the thumbnail images
  • adjust the logic to consider each image type
• I will request review from your side

My idea is to add a multiselect field which is used for enabling / disabling the image types. What do you think about that approach? This would allow for easy configuration regarding the image types that should be resized.

I believe it works best for Hyvä Storefronts - but this implementation is not logically theme dependent. I have tested locally, that the $viewConfig seems to always retrieve the aggregated data of the theme that is selected for the default website. I confirmed that it also works for Luma.
