Simplify class inheritance

Overview

Simplify class inheritance

Before

class CRM_Contribute_Import_Parser_Contribution extends CRM_Contribute_Import_Parser {

After

Functions from CRM_Contribute_Import_Parser moved to CRM_Contribute_Import_Parser_Contribution so everything is on the same class.

Technical Details

CRM_Contribute_Import_Parser_Contribution is the only class in our universe to
extend CRM_Contribute_Import_Parser and this class only adds confusion to the
mix as functions are 'distributed' between them

Simplification makes sense. There's no real purpose to using an abstract class just once, it might as well not exist.
