If Param->evaluateValue() can evaluate it it will set the default value in
FormatFunctionParameter (that means it's a primitive type like "void func(int i
= 0)").
In case it's some kind of non-primitive type like "void func(Foo foo = Foo(0,
0))" it will not be evaluated and we can use here the source manager to get the
default value string. In this example it will be Foo(0, 0).
