[RFC] Support object types in BCMath (#13741)
Added BcMath\Number class. It is an immutable object, has methods that are
equivalent to existing BCMath calculation functions, and can also be calculated
using operators.

The existing BCMath function returned a string for each calculation, but this
class returns an object.
