[Feature Request][SPARK] Make Vacuum DRY RUN list all the files along with the the size of the files

Feature request

Which Delta project/connector is this regarding?

• Spark
• Standalone
• Flink
• Kernel
• Other (fill in here)

Overview

As of now, Vacuum dry run mode returns a dataframe containing a list of first 1000 files to be deleted. Instead, it's more useful to return all the eligible files to be deleted along with the size of these files.

Motivation

Today, users run Vacuum in dry run mode to understand the eligible files and the size of the data that is going to be deleted. By returning only a sample of 1000 files, users are not able to achieve their objective.
