Rollup merge of #137333 - compiler-errors:edition-2024-fresh, r=Nadrieril

Use `edition = "2024"` in the compiler (redux)

Most of this is binding mode changes, which I fixed by running `x.py fix`.

Also adds some miscellaneous `unsafe` blocks for new unsafe standard library functions (the setenv ones), and a missing `unsafe extern` block in some enzyme codegen code, and fixes some precise capturing lifetime changes (but only when they led to errors).
