@rfcbot reviewed

I agree that dyn compatible is a better term to describe which traits may be used with dyn. Specifically, I'd probably frame it that dyn-safety / trait object safety is something that Rust ensures, and that what it requires from users is that they write dyn compatible traits.

I'll open draft PRs for rustc and the std lib shortly.

Compiler: Rename "object safe" to "dyn compatible"

Completed T-lang FCP: rust-lang/lang-team#286 (comment).
Tracking issue: rust-lang#130852

Excludes `compiler/rustc_codegen_cranelift` (to be filed separately).
Includes Stable MIR.

Regarding https://github.com/rust-lang/rust/labels/relnotes, I guess I will manually open a https://github.com/rust-lang/rust/labels/relnotes-tracking-issue since this change affects everything (compiler, library, tools, docs, books, everyday language).

rustdoc: Rename "object safe" to "dyn compatible"

Supersedes rust-lang#126554:

1. In line with [T-lang's latest resolution](rust-lang/lang-team#286 (comment)).
2. More comprehensive: Not only updates user-facing text but also source code.

Part of rust-lang#130852.

Doesn't update rustdoc-JSON (will be filed separately).
