Lintcheck: Rework and limit diff output for GH's CI

### Background

While working on https://github.com/rust-lang/rust-clippy/pull/13136 I found an amazing limitation of GH's CI. The summary can at most have be 1MB of text. Here is the warning message:

> $GITHUB_STEP_SUMMARY upload aborted, supports content up to a size of 1024k, got 46731k. For more information see: https://docs.github.com/actions/using-workflows/workflow-commands-for-github-actions#adding-a-markdown-summary

[The PR](https://github.com/rust-lang/rust-clippy/pull/13136) produced a *casual* 61808 changes. Guess that's why those lints are not *warn-by-default* :P.

### Changes:

This PR limits the lintcheck diff output in two ways.

1. The diff is limited to 200 messages per lint per section. Hidden messages are indicated by a message at the end of the section.
2. The output is first written to a file and only the first 1MB is written to ` >> $GITHUB_STEP_SUMMARY`. The entire file is also written to the normal CI log. This helps for cases where several lints change and the total size exceeds the 1MB limit.

An example of these changes can be seen here: https://github.com/xFrednet/rust-clippy/actions/runs/10028799118?pr=4
