What does this PR do?

Gracefully avoids some out-of-memory edges that can happen in ProfileExporter::build.

Motivation

I got a crash report in the PHP profiler which OOM'd here trying to push_str.

Technically, this is a slight optimization as well but this will definitely be inconsequential.

Additional Notes

This doesn't fix all OOMs or even anything remotely close to it. It just moves the needle a teensy bit and was not difficult to do.

Also note that try_reserve doesn't mess up allocation amortization, we'd have to use try_reserve_exact for that. We do use try_reserve_exact for the last tag, though, as a slight optimization.

How to test the change?

Regular tests apply.
