Rollup merge of rust-lang#118642 - Xanewok:patch-1, r=clubby789

bootstrap(builder.rs): Don't explicitly warn against `semicolon_in_expressions_from_macros`

This already wasn't passed in bootstrap.py and the lint itself already warns-by-default for 2 years now and has already been added to the future-incompat group in Rust 1.68.

See rust-lang#79813 for the tracking issue.
