Summary: changelog: [internal] For some reason, using `TextLayoutManager::Shared` in `TextInputShadowNode` trips up clang tidy linter. We have a plan to move away from `*::Shared` anyway, so let's remove it from `TextInputShadowNode` now. Why do we want to move away from `*::Shared`? Using `TextLayoutManager::Shared` is confusing for people unfamiliar with Fabric's codebase. It expresses a concept of immutability but uses term `shared`. Term shared is already used in C++ `std::shared_ptr`. Reviewed By: fkgozali Differential Revision: D33186422 fbshipit-source-id: 10ee588735997f5fedc372a1d1e3d9cd9684178a
