Summary:
These `constexpr` template variables make it really easy to test for bridging conversion to/from the specified types. The unit tests for this actually uncovered a bug with incompatible casts from lvalue references that was fixed in this diff as well.

Summary:
This adds the *option* for C++ TurboModules to use a `*CxxSpec<T>` base class that extends the existing (and unchanged) corresponding `*CxxSpecJSI` base class with code-generated methods that use `bridging::calFromJs` to safely convert types between JSI and C++. If a type conversion cannot be made, then it will fail to compile.

Summary:
This adds `bridging::callFromJs` that can call class instance methods with JSI arguments and will automagically convert types to the types expected by the method, or otherwise will fail to compile. The same type conversion back to JSI applies as well for the return value, if there is one.
This will allow C++ TurboModules to more easily define their interface in terms of C++ types instead of having to interact with JSI directly for everything, though it remains possibles for JSI values to pass through if that's what a given method wants.
