Add parametrised test suites

[ilg-ul]

Accept something like:

static void
test_suite_args (int ic, int iv, int& ir, int* ip1, int* ip2)
{
  using namespace micro_os_plus::micro_test_plus;

  test_case ("args", [&] {
    expect (eq (ic, 42)) << "ic is 42";
    expect (eq (iv, 43)) << "iv is 43";
    expect (eq (ir, 44)) << "ir is 44";
    expect (eq (*ip1, 45)) << "*ip1 is 45";
    expect (eq (*ip2, 46)) << "*ip2 is 46";
  });
}

static int in = 43;
static int in44 = 44;
static int& ir = in44;
static int in45 = 45;
static int in46 = 46;
static int* ip2 = &in46;

static micro_os_plus::micro_test_plus::test_suite ts_args
    = { "Args", test_suite_args, 42, in, ir, &in45, ip2 };
