Add comments and avoid using shared_ptr unnecessarily.
Why note shared_ptr? Using shared_ptr suggests we are transferring ownership of object, which we are not.

Summary:
Refactors MapBuffer-related `primitives.h` to be namespaced with `MapBuffer` class, to avoid name collisions and confusion later on.
Most of the size constants are moved to relevant .cpp files or updated to use `sizeof`.
Additionally, adds a little bit of documentation about `MapBuffer` serialization format.

Summary:
Serializes type information along with key/value in MapBuffer, asserting the data type on Java side during read. At the moment, accessing value with incorrect will result in a crash.
Other changes:
Adds a `getType` method to verify types before accessing them.
Removes `null` as a type, as just not inserting value and checking for its existence with `hasKey` is more optimal.

Summary:
Replaces dynamic manually managed array with a vector of bytes, removing the need for managing memory manually.
This approach is a little bit slower than before, as vector is allocating memory more conservatively. This can be improved in the future by providing an estimate for the data size.

Summary:
Instead of copying integer values into key/value data array, this implementation keeps a structured vector of `Bucket` structs (which is sized to be serialized later).
This approach provides multiple benefits to modify and access buckets (e.g. sort them based on the key, allowing for out of order inserts (D33611758))

You can read more about this rule on https://clang.llvm.org/extra/clang-tidy/checks/modernize-pass-by-value.html
# Isn't it wasteful to copy? Isn't reference more efficient?
This rule of thumb is no longer true since C++11 with move semantics. Let's look at some examples.
# Option one
```
class TextHolder
{
public:
TextBox(std::string const &text) : text_(text) {}
private:
std::string text_;
};
```
By using reference here, we prevent the caller from using rvalue to and avoiding copy. Regardless of what the caller passes in, copy always happens.
# Option two
```
class TextHolder
{
public:
TextBox(std::string const &text) : text_(text) {}
TextBox(std::string &&text) : text_(std::move(text)) {}
private:
std::string text_;
};
```
Here, we provide two constructors, one for const reference and one for rvalue reference. This gives the caller option to avoid copy. But now we have two constructors, which is not ideal.
# Option three (what we do in this diff)
```
class TextHolder
{
public:
TextBox(std::string text) : text_(std::move(text)) {}
private:
std::string text_;
};
```
Here, the caller has option to avoid copy and we only have single constructor.

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`.
