Summary:
* Now all `RCTViewComponentView` subclasses are required to set `_props` instance variable in the constructor with a default value;
* `RCTViewComponentView`'s `_props` instance variable now has `ShadredViewProps` type (that enforced by `static_assert` in `ConcreteViewShadowNode` template);
* New we use `static_pointer_cast` instead of `dynamic_pointer_cast` for casting props.

Summary:
@public
After reading about move-semantic and rvalue refs I realized that we (I) definitely overuse `auto &&` (aka universal reference) construction. Even if this is harmless, does not look good and idiomatic.
Whenever I used that from a semantical point of view I always meant "I need an alias for this" which is actually "read-only reference" which is `const auto &`.
This is also fit good to our policy where "everything is const (immutable) by default".
Hence I change that to how it should be.
