feat: always build the processinfo temp dir

[isaacs]

Always build the processinfo data directory (with index) in
${tmpdir}/processinfo. This more easily supports cases where the
processinfo index may be useful for later analysis, or generating the
process tree post hoc.

BREAKING CHANGE: this removes the --build-process-tree option, which
appeared in previous 14.0.0 prerelease versions.

All of my comments below the line assume nobody has objections to always building the processinfo files. I'm OK with it but want to give others a chance to speak. @bcoe @JaKXz @addaleax?

This will not be labeled as a breaking change. I plan to delete "add --build-process-tree feature" from the new features section of the changelog to prevent confusion. 14.0.0-alpha.0 was a non-tagged release so when we eventually do the final 14.0.0 release the changelog will be generated as if no pre-release versions were created (all changes between 13.3.0 and 14.0.0 will be listed as new to 14.0.0).

The cleanest way to handle this would be to revert #1028 in a separate commit to master and merge those changes into this PR. Then when standard-version generates the changelog it would see the revert and ignore #1028.

Further detail: we don't have strictness enabled in yargs, so nyc --build-process-tree will continue to work without error and the process tree will be build.

seems reasonable to me 👍 @coreyfarrell feel free to edit the CHANGELOG liberally, it's meant to be a convenience not the law.

Very happy to be the one to help obliterate my previous contribution ;)
