Adds support for LTO on macOS and Android. Disable LTO by default on iOS even if `production=yes` is set. Also add `linker` option to `server` platform missed in #63283. Refactor code handling old arguments to make it simpler (breaks compat, but is explicit enough about it and scripts are easy to fix).
