diagnostics: move/rename output formats to diagnostics as "sinks"

Within gcc/
  move diagnostic-buffer.h to diagnostics/buffering.h
  move diagnostic-format-html.cc to diagnostics/html-sink.cc
  move diagnostic-format-html.h to diagnostics/html-sink.h
  move diagnostic-format-sarif.cc to diagnostics/sarif-sink.cc
  move diagnostic-format-sarif.h to diagnostics/sarif-sink.h
  move diagnostic-format.h to diagnostics/sink.h
  move diagnostic-format-text.cc to diagnostics/text-sink.cc
  move diagnostic-format-text.h to diagnostics/text-sink.h

renaming various types including:
  Old name:                       New name:
  diagnostic_output_format        diagnostics::sink
  diagnostic_buffer               diagnostics::buffer
  diagnostic_per_format_buffer    diagnostics::per_sink_buffer
  diagnostic_text_output_format   diagnostics::text_sink
  sarif_output_format             diagnostics::sarif_sink
  diagnostic_sarif_format_buffer  diagnostics::sarif_sink_buffer
  html_output_format              diagnostics::html_sink
  diagnostic_html_format_buffer   diagnostics::html_sink_buffer

No functional change intended.
