Support memory report logs with interleaved non-report output
<!-- Please describe your changes on the following line: -->
`line 30-31` in `servo/etc/memory_reports_over_time.py` should just ignore any line that doesn't begin with `|`.
The new if statement added such as `if line.startswith('|'):` then continue to append. So, only lines begin with `|` will be appended.

Don't use unsafe Heap::new constructor
<!-- Please describe your changes on the following line: -->
Pulls https://github.com/servo/rust-mozjs/pull/398 and aims to close https://github.com/servo/rust-mozjs/issues/343.
We can't convert from `JSVal` to `Heap<JSVal>` safely (due to GC barriers we can't move Heap value after changing its underlying value to something meaningful, e.g. non-null or non-undefined), so I decided to also wrap the Heap values in a Box (and in dictionaries in RootedTraceableBox, see https://github.com/servo/servo/pull/20265#issuecomment-372838379 and the issue for more details) in dictionaries.
Since we allocate more to be safe, I think it'd be good to also do some sort of a JS perf run, if there is any to see if there's any significant overhead.

<!-- Either: -->

Remove update-manifest argument that is no longer valid.
This nightly sync job is now broken since #20312 because it doesn't need to select a particular binary. We can get rid of the unnecessary argument to fix it.
