Improved: ‘ObjectType’ contains unneeded code

(OFBIZ-10771)

The ObjectType class contains utilities that extends the Java reflection API by 
defining methods which accepts string representation of Java types and classes.
It appears that this class contains unneeded code which is either dead or is 
redundant with the services already defined in the reflection API

Removes the useless isOrSubOf, instanceOf and interfaceOf methods. 
Additionally it removes the getInstance method which is not used anywhere in 
the framework or in the plugins.

Also includes similar changes in 
AbstractConverter.java
Converters.java 
DateTimeConverters.java 
GenericEntity.java
IfInstanceOf.java
