Summary:
This diff fixes a redbox happens on every single hot-reload practically saying that ImageLoader is misconfigured. The issue happened because after reloading Fabric used the previous obsolete instance of `ImageLoader` created and stored inside old (and already destroyed) instance of Bridge. The fix is simple: We update all dependencies after the Bridge was reloaded.

Summary: Right now RuntimeExecutor is only used in Fabric. Moving it out of Fabric's uimanager/primitives.h and into react/utils so we can use it more broadly.

Summary:
... and slighly new behaviour for one of them.
The method does nothing if given `key` already exists in the container.
This diff finishes the transition of ContextContainer from an internal bag of things with unclear yet ownership into a legit dedicated dependency injection container for the product code.
The original names of methods imply that the container can have only one object of a given type which is no longer true. The new API is much more generic and idiomatic to C++, it mimics `std:map` API which is intuitive to anyone who familiar with C++ containers.
Besides the naming, `insert` method changed the semantic a bit; now it does nothing in case of inserting an object with a key that already exists. That might seem counterintuitive for "normal" people, but C++ has some wired reasons for that and, hopefully, it's expected behavior in the C++ community.
Fun fact: We need this to fix hot-reload.

Summary:
First of all, seems it's the right thing to do. Fabric C++ code is cross-platfrom and should run on *all* platforms including Windows, Linux, and Mac.
While we don't have a real *production* use cases where we need compilation for desktops, having CXX target is really handy for two reasons:
* It simplifies local test running process. Instead of going to `/fbandroid/` and executing something like `buck test fbsource//xplat/js/react-native-github/ReactCommon/fabric/core:coreAndroid` (note the suffix). We can just do `buck test fbsource//xplat/js/react-native-github/ReactCommon/fabric/core:core` everywhere and it works now out of the box. Running tests with "Apple" flavor never worked for me.
* It allows creating synthetic benchmark tests (using Google Benchmark) that can be used as a rough approximation of code micro-optimizations.

Summary:
In ContextContainer, only in Debug mode, we store type information alongside with data to detect typemismatch in runtime. We used type hashes before, but seems they are not so stable and can cause some false negative crashes.
This diff changes that to store mangled typenames instead of hashes, so it should be much more reliable now.

Summary: Sometimes we don't know for sure if `ContextContainer` has a value or not (and that's perfectly legit use case). In those cases now we can use `findInstance` method that returns an optional intead of throwing an exeption.

Summary:
`SharedFunction` implements a pattern of a shared callable object that contains the same executable inside. It's similar to `std::function` with one important difference: when the object is copied, the stored function (and captured values) are shared between instances (not copied).
`SharedFunction` can be stored inside `std::function` because it's callable.
It useful in some scenarios, such as:
* When captured by `std::function` arguments are not copyable;
* When we need to replace the content of the callable later on the go.
We will use it in the coming diffs.
