### What changes were proposed in this pull request?
<!--
Please clarify what changes you are proposing. The purpose of this section is to outline the changes and how this PR fixes the issue.
If possible, please consider writing useful notes for better and faster reviews in your PR. See the examples below.
1. If you refactor some codes with changing classes, showing the class hierarchy will help reviewers.

3. If there is design documentation, please add the link.
4. If there is a discussion in the mailing list, please add the link.

Compute the schema of the data without partition columns only once in FileSourceStrategy.
### Why are the changes needed?
<!--
Please clarify why the changes are needed. For instance,
1. If you propose a new API, clarify the use case for a new API.
2. If you fix a bug, you can clarify why it is a bug.
-->
In FileSourceStrategy, the schema of the data excluding partition columns is computed 2 times in a slightly different way, using an AttributeSet (`partitionSet`) and using the attributes directly (`partitionColumns`) These don't have the exact same semantics, AttributeSet will only use expression ids for comparison while comparing with the actual attributes will use the name, type, nullability and metadata. We want to use the former here.
### Does this PR introduce _any_ user-facing change?
<!--
Note that it means *any* user-facing change including all aspects such as the documentation fix.
If yes, please clarify the previous behavior and the change this PR proposes - provide the console output, description and/or an example to show the behavior difference if possible.
If possible, please also clarify if this is a user-facing change compared to the released Spark versions or within the unreleased branches such as master.
If no, write 'No'.
-->
No
### How was this patch tested?
<!--
If tests were added, say they were added here. Please make sure to add some test cases that check the changes thoroughly including negative and positive cases if possible.
If it was tested in a way different from regular unit tests, please clarify how you tested step by step, ideally copy and paste-able, so that other reviewers can test and check, and descendants can verify in the future.
If tests were not added, please describe why they were not added and/or why it was difficult to add.

It's fine to skip 3.4 as https://github.com/apache/spark/pull/46565 was not merged to 3.4 either.

This fixes a regression caused by https://github.com/apache/spark/pull/46565/files#diff-fbc6da30b8372e4f9aeb35ccf0d39eb796715d192c7eaeab109376584de0790eR121 , and make Delta Lake pass all tests. I think we should include it in 3.5.2. cc @yaooqinn
