diagnostics: group together source printing fields of diagnostic_context

struct diagnostic_context has > 60 fields.

Try to tame some of the complexity by grouping together the 8
source-printing fields into a struct, the "m_source_printing" field.

No functional change intended.

	of diagnostic_context's show_caret to m_source_printing.enabled.
