Fabric: Embracing non-trivial default values of some Props

Summary:
@public
This is follow up for D8601600 and D8247652 (the last one has detailed explanation of the problem).
From this commit I propose that we have to follow simple rule:
If some prop has a default value which differs from the default value of its type, we have to specify it as {<value>} in .h file and explicitly in .m file, for all other props the default value must not be specified explicitly (in .h files it must be specified as {}).
The reason is that we have to embrase those cases and establish behaviour: if we change the default value in .h file, it always means that we have to change the value in .cpp file too.
