Rollup merge of #119388 - Enselic:prevent-lint-triplication, r=cjgillot

rustc_lint: Prevent triplication of various lints

Prevent triplication of various lints. The triplication happens because we run the same lint three times (or less in some cases):
* In `BuiltinCombinedPreExpansionLintPass`
* In `BuiltinCombinedEarlyLintPass`
* In `shallow_lint_levels_on()`

Only run the lints one time by checking the `lint_added_lints` bool.

Set your GitHub diff setting to ignore whitespaces changes when reviewing this PR, since I had to enclose a block inside an if.

Closes #73301

(I found this while exploring the code related to [this](https://github.com/rust-lang/rust/pull/119251#discussion_r1435677330) comment.)
