Adam Comella b747286c1d Fix C# unit tests (#818)
Summary:
This consists of several fixes:
  - Some of the C++ functions called by the tests were missing `WIN_EXPORT`
  - It looks like Yoga was changed to round up after `TestMeasureFuncWithFloat` was written. Here's the function call that results in the rounding: 357ca78f9f/yoga/Yoga.cpp (L4019-L4026)
  - The format of the result of the `Print` method was changed after `TestPrint` was written.
