[Issue] Refactor moveFileFromTmp to not use a static method call

[m2-assistant]

This issue is automatically created based on existing pull request: #27581: Refactor moveFileFromTmp to not use a static method call

---

Summary (*)

Magento 2.4-develop
Currently the class \Magento\Catalog\Model\ImageUploader has a static call to Uploader::getNewFileName

In this PR I plan to:

• Create new class for the method getNewFileName,
• Refactor the \Magento\Catalog\Model\ImageUploader class to use this new class,

Examples (*)

1. Upload an image to a category with a unique name and check that name has not been changed,
2. Upload an image to a category with a nonunique name and check that the name has been updated to be unique,

Proposed solution

I am not too sure on the naming of the new class but would be happy to update it if needed.
I am also not sure about if I need an optional injection of my new class to the ImageUploader class.
