scroggo 0ee2627026 When running DM, write test failures to json.
Add skiatest::Failure to keep track of data about a test failure.

Reporter::reportFailed and ::onReportFailed now take Failure as a
parameter. This allows the implementation to treat the failure as it
wishes. Provide a helper to format the failure the same as prior to
the change.

Update the macros for calling reportFailed (REPORTER_ASSERT etc) to
create a Failure object.

Convert a direct call to reportFailed to the macro ERRORF.

Write Failures to Json.
Sample output when running dm on the dummy test crrev.com/705723004:
{
   "test_results" : {
      "failures" : [
         {
            "condition" : "0 > 3",
            "file_name" : "../../tests/DummyTest.cpp",
            "line_no" : 10,
            "message" : ""
         },
         {
            "condition" : "false",
            "file_name" : "../../tests/DummyTest.cpp",
            "line_no" : 4,
            "message" : ""
         },
         {
            "condition" : "1 == 3",
            "file_name" : "../../tests/DummyTest.cpp",
            "line_no" : 5,
            "message" : "I can too count!"
         },
         {
            "condition" : "",
            "file_name" : "../../tests/DummyTest.cpp",
            "line_no" : 6,
            "message" : "seven is 7"
         },
         {
            "condition" : "1 == 3",
            "file_name" : "../../tests/DummyTest.cpp",
            "line_no" : 14,
            "message" : "I can too count!"
         }
      ]
   }
}

Report all of the failures from one test.
Previously, if one test had multiple failures, only one was reportered.
e.g:

Failures:
  test Dummy: ../../tests/DummyTest.cpp:6   seven is 7
  test Dummy2: ../../tests/DummyTest.cpp:10 0 > 3
  test Dummy3: ../../tests/DummyTest.cpp:14 I can too count!: 1 == 3
3 failures.

Now, we get all the messages:

Failures:
  test Dummy: ../../tests/DummyTest.cpp:4   false
        ../../tests/DummyTest.cpp:5 I can too count!: 1 == 3
        ../../tests/DummyTest.cpp:6 seven is 7
  test Dummy2: ../../tests/DummyTest.cpp:10 0 > 3
  test Dummy3: ../../tests/DummyTest.cpp:14 I can too count!: 1 == 3
3 failures.

(Note that we still state "3 failures" because 3 DM::Tasks failed.)
