PdfPerfPhase enum

Timed phases. Enum-indexed so recording is string-free and alloc-free.

A phase accumulates inclusive wall time across all its begin/end pairs; nested phases (e.g. flate inside docOpen) each count their own time, so phase sums can exceed end-to-end wall time. Compare a phase with itself across runs, not phases against each other as a partition.
