Moved YGFloatOptional from C struct to C++ struct

Browse Source 
Summary:
Earlier `YGfloatOptional` was plain struct with no privacy around the variables. This diff adds privacy and also enforces checks when one tries to access value of an undefined `YGFloatOptional`

This diff also adds a behaviour in which when a value of an undefined YGFloatOptional is accessed, it will normally terminate(Several cleanup steps are performed).
