IDL compiler: remove redundant '_name' from template parameters

IDL compiler: remove redundant '_name' from template parameters

'_name' is redundant in template parameter names (it's just string
substitution), so this removes it, primarily simplifying:
{{cpp_class_name}} => {{cpp_class}}
{{v8_class_name}} => {{v8_class}}
This helps readability a lot, as these are really common.
(Discussed previously.)
