Adding gtest helpers for BeginFrameArgs.

 * Allow BeginFrameArgs inside an EXPECT_EQ call.
    EXPECT_EQ(args1, args2)

 * Allow gtest to pretty print BeginFrameArgs objects.

   Output use to look like;
---------------------------------------------------
    Expected: args1
    Which is:
      16 byte object <0xFF 0xFF 0xFF 0x01 ...>

    Actual: args2
    Which is:
      16 byte object <0xFF 0xFF 0xFF 0x01 ...>
---------------------------------------------------

   Output now looks like;
---------------------------------------------------
    Expected: args1
    Which is:
     BeginFrameArgs(1, 2, 3)

    Actual: args2
    Which is:
     BeginFrameArgs(1, 2, 4)
---------------------------------------------------
