SAX::Parser constructors check types (v1.13.x branch)

---

**What problem is this PR intended to solve?**

HTML4::SAX::Parser, HTML4::SAX::ParserContext, XML::SAX::Parser, and XML::SAX::ParserContext now properly check the types of the arguments to their various constructor methods.

Previously, passing arguments of unexpected types might cause a segfault or other less-obvious exceptions.

This is a backport of #2529 


**Have you included adequate test coverage?**

Yes! Added test coverage for these cases.


**Does this change affect the behavior of either the C or the Java implementations?**

Both the C and Java implementations have been updated to behave identically in this circumstance.
