diagnostics: introduce diagnostics/source-printing.cc

Move diagnostic-show-locus.cc to diagnostics/source-printing.cc

Move diagnostic-label-effects.h to diagnostics/source-printing-effects.h

Move selftest-diagnostic-show-locus.h
  to diagnostics/selftest-source-printing.h

No functional change intended.

gcc/ChangeLog:
	* Makefile.in (OBJS): Replace diagnostic-show-locus.o with
	diagnostics/source-printing.o.
	* diagnostic.h (class diagnostic_source_effect_info): Replace
	with...
	(class diagnotics::source_effect_info): ...this.
	* diagnostics/paths-output.cc: Likewise.  Update for move of
	"diagnostic-label-effects.h" to
	"diagnostics/source-printing-effects.h".
	* diagnostics/sarif-sink.cc: Update for move of
	"selftest-diagnostic-show-locus.h" to
	"diagnostics/selftest-source-printing.h".
	* selftest-diagnostic-show-locus.h: Move to...
	* diagnostics/selftest-source-printing.h: ...here.
	* diagnostic-label-effects.h: Move to...
	* diagnostics/source-printing-effects.h: ...here, updating
	for above changes.
	* diagnostic-show-locus.cc: Move to...
	* diagnostics/source-printing.cc: ...here.
	* gcc-rich-location.h: Likewise.
	* selftest-run-tests.cc: Likewise.
	* selftest.h: Likewise.

gcc/testsuite/ChangeLog:
	* g++.dg/plugin/show-template-tree-color-labels.C: Update for
	moves to "source-printing".
	* gcc.dg/plugin/diagnostic-test-show-locus.py: Likewise.

libcpp/ChangeLog:
	* include/cpplib.h: Update for moves to "source-printing".
	* include/rich-location.h (class label_effects): Move to...
	(class diagnostics::label_effects): ...here.
