Summary:
@public
Adds `_pt` and `_percent` user defined literals to create `YGValue` instances.
This allows to create `YGValue`s in the following form:
```
use namespace facebook::yoga::literals;
auto a = 123_pt; // == YGValue{123.0f, YGUnitPoint}
auto b = -12.5_percent; // == YGValue{-12.5f, YGUnitPercent}
```
