Auto merge of #96790 - lqd:update_jemalloc, r=Mark-Simulacrum

Update jemalloc to v5.3

Now that `jemalloc` version 5.3 has been released, this PR updates `tikv-jemalloc-sys` to the corresponding release.

The crates.io publishing issue seems to have been resolved for the `jemalloc-sys` package, and version 5.3.0 is now also available under the historical name (and should become the preferred crate to be used). Therefore, this PR also switches back to using `jemalloc-sys` instead of  `tikv-jemalloc-sys`.
