### What does this PR try to resolve? This PR conditionally mark the `test` cfg as a well known cfg depending on the target unit "test" field (ie `lib.test = false`, `[[bin]] test = false` and others). This is related to rust-lang/rust#117778 and https://users.rust-lang.org/t/cargo-what-is-the-purpose-of-lib-test-false/102361. When defining `lib.test = false` (and others), any use of `cfg(test)` will trigger the `unexpected_cfgs` lint. ```toml [lib] test = false # will now warn on cfg(test) ``` ### How should we test and review this PR? Best reviewed commit by commit. Second commit removes the `test` cfg from the `--check-cfg` args. ### Additional information T-compiler [MCP#785](rust-lang/compiler-team#785) and #14963 were of preparatory work. r? @epage

What does this PR try to resolve?
This PR adds the
testcfg as a well known Cargo cfg as rust-lang/compiler-team#785 is now in FCP and before the compiler change.How should we test and review this PR?
Look at the new argument passed and the test changes.
Additional information
Detailed motivation at rust-lang/compiler-team#785, but summary
testis a weird well known cfg forrustcas it's mostly a convention and build system like Cargo may to set it conditionally (lib.test = falsefor Cargo, not done in this PR).Pre-require to rust-lang/rust#131729.
