This replaces existing use of core SPL exceptions with the equivalent classes defined within the component. Although method documentation has been changed, this change should be BC since the component-specific SPL exceptions extend their core counterpart.
This commit purposely omits any changes to the PhpDumper, which throws several core SPL exceptions.
Previously, the Definition class was used both for type inference and factory construction (if factoryService was absent). This is fine for cases where classes create instances of themselves (e.g. getInstance() or create()), but leads to ambiguity when we have a separate factory class.
