Auto merge of #18944 - servo:jemallocator2, r=nox

Stop relying on linking details of std’s default allocator

We’ve been bitten before by symbol names changing: https://github.com/servo/heapsize/pull/46, and upstream is planning to stop using jemalloc by default: https://github.com/rust-lang/rust/issues/33082#issuecomment-309781465

So use the (relatively) new `#[global_allocator]` attribute to explicitly select the system allocator on Windows and jemalloc (now in an external crate) on other platforms. This choice matches current defaults.
