diagnostics: rename dc.printer to m_printer [PR116613]

Rename diagnostic_context's "printer" field to "m_printer",
for consistency with other fields, and to highlight places
where we currently use this, to help assess feasibility
of supporting multiple output sinks (PR other/116613).

No functional change intended.
