Moved CC_SYNTHESIZE and CC_PROPERTY macros onto a single line (#17765)

This permits comments to be visible in tooltips for the variable and it's associated accessor functions

e.g.
//The health of the entity, when this reaches zero the entity is dead
CC_SYNTHESIZE(float, m_health, Health)

Previously the above comment would only be displayed in the tooltip for the member variable
