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

Completed T-lang FCP: https://github.com/rust-lang/lang-team/issues/286#issuecomment-2338905118.
Tracking issue: https://github.com/rust-lang/rust/issues/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).
