What's in 1.67.1 stable

Rust 1.67.1 fixes a regression for projects that link to 
thin archives (.a files that reference external .o objects). 
The new archive writer in 1.67.0 could not read thin 
archives as inputs, leading to the error ""Unsupported archive identifier."" The compiler now uses LLVM's archive writer 
again, until that format is supported in the new code.

Additionally, the clippy style lint uninlined_format_args is temporarily downgraded to pedantic -- allowed by default. 
While the compiler has supported this format since 
Rust 1.58, rust-analyzer does not support it yet, so it's not necessarily good to use that style everywhere possible.

The final change is a soundness fix in Rust's own bootstrap 
code. This had no known problematic uses, but it did raise 
an error when bootstrap was compiled with 1.67 itself, 
rather than the prior 1.66 release as usual.
