diagnostics: consolidate group-handling fields in diagnostic_context

No functional change intended.

gcc/ChangeLog:
	* diagnostic.cc (diagnostic_initialize): Update for consolidation
	of group-based fields.
	(diagnostic_report_diagnostic): Likewise.
	(diagnostic_context::begin_group): New, based on body of
	auto_diagnostic_group's ctor.
	(diagnostic_context::end_group): New, based on body of
	auto_diagnostic_group's dtor.
	(auto_diagnostic_group::auto_diagnostic_group): Convert to a call
	to begin_group.
	(auto_diagnostic_group::~auto_diagnostic_group): Convert to a call
	to end_group.
	* diagnostic.h (diagnostic_context::begin_group): New decl.
	(diagnostic_context::end_group): New decl.
	(diagnostic_context::diagnostic_group_nesting_depth): Rename to...
	(diagnostic_context::m_diagnostic_groups.m_nesting_depth):
	...this.
	(diagnostic_context::diagnostic_group_emission_count): Rename
	to...
	(diagnostic_context::m_diagnostic_groups::m_emission_count):
	...this.
