test: add core-specific varlink enum sync test

Add test-varlink-idl-unit that validates all varlink enum types in
io.systemd.Unit match their corresponding C string tables. This
catches drift between varlink IDL enum definitions and internal
enum values.

Uses core_test_template since it links against libcore for access
to the string table lookup functions.

ExecOutput uses TEST_IDL_ENUM_TO_STRING only because the '+' in
'kmsg+console' doesn't survive the underscorify/dashify round-trip.
