Remove ancient "phd.trace" and "phd.verbose" configuration options

Summary:
Ref T13556. These options are very old and effectively obsoleted by "bin/phd debug [--trace]". I haven't used either option diagnostically in many years, and they aren't mentioned in the documentation.

Remove them to simplify configuration, and because "phd.trace" doesn't work anyway and likely hasn't for a long time -- it has specific issues with TTY detection (see T13556).

Test Plan: Grepped for "phd.trace" and "phd.verbose". Ran "bin/phd debug [--trace]" and saw verbose/trace output.
