GlueGen: Type: Have get{Base,Target}Type() stop at isFunctionPointer(), enhance API doc; Add getArrayBaseOrPointerTargetType() and getTargetFunction()

Added getArrayBaseOrPointerTargetType() returns getBaseType() for arrays or getTargetType() for pointer,
i.e. stops traversing if an elementType is a pointer and returns the elementType as target-type.
This resolves 'int* intPtrArray[10]', but also simplifies all cases of 'int** intPtrPtr' and 'int intPtr[10]' etc.

Since get{Base,Target}Type() returns the functionPointer, getTargetFunction() allows to retrieve the actual target function type.
