`Base.depwarn` logs through the active logger, and the I/O involved can switch tasks. That is illegal while holding the typeinf lock, which our `@locked` compilation entry points do on Julia 1.10/1.11, and caused hangs (#830). Replace it with `safe_depwarn`, which writes the warning synchronously to `Core.stderr` like `@safe_warn` does. Caller attribution, warning once per call site, and throwing under `--depwarn=error` still behave like `Base.depwarn`; on 1.12+, where compilation doesn't hold the typeinf lock, it just forwards there.
