Instead of a hand-rolled discriminated union (originally used to avoid a C++17 dependency, which is no longer an issue), implement EncodableValue as a std::variant. Rather than simply changing the internals, this makes EncodableValue a minimal std::variant subclass with only a handful of added methodS, replacing the old IsFoo/FooValue APIs with the standard std::holds_alternative/std::get, so that plugin code will use a standard-based API rather than a Flutter-specific API for wrapped values. This is a breaking change for Windows and GLFW plugins. In the short term USE_LEGACY_ENCODABLE_VALUE can be set in builds to use the old version, to separate rolling from updating. Fixes https://github.com/flutter/flutter/issues/61970
