feat(prof): build with panic=abort, std too

[morrisonlevi]

Description

This is an experiment that builds on Florian's feat(prof): switch panics to abort so that it also builds std with panic_abort. This should give us more helpful stack traces on panics.

For reasons that are unclear, this comes out larger than merely doing panic=abort and not rebuilding std. I could not get bloaty to build in multiple different containers, so I don't know why. Let's just ship panic=abort for now.
