Access innerTextElement by ID.

ID access is safer than holding a RefPtr because an element accessed by its ID
is always in a DOM tree.

- We need to keep HTMLTextFormControlElement::innerTextElement()
  because some classes call it.
- The ID name is "inner-editor", not "innerTextElement" or something like it.
  "innerTextElement" is confusing with Element::innerText. We're going to rename
  it later.

BUG=none
TEST=Update existing automated tests for internal markup changes.

IDL compiler: rename data_type => idl_type

In the CG we use |idl_type| for IDL types, to contrast with C++ types.
For consistency, use |idl_type| in parser as well.

This is just:
sed -i 's/data_type/idl_type/g' *.py
