Michael Weghorn 671b8cad97 a11y: Rename OAccessibleComponentHelper to OAccessible 
The helper class used to implement less functionality
in the past and was used less than it is now.
But by now it is the central helper/base class used
by most a11y classes.

Since

    commit 22049f633b
    Author: Michael Weghorn <m.weghorn@posteo.de>
    Date:   Mon May 26 12:24:52 2025 +0200

        vcl a11y: Let OAccessibleComponentHelper implement XAccessible

it also implements the XAccessible interface.

That will allow to switch parameters and class members
from the abstract XAccessible interface to using this
more concrete C++ base class in various places.

Rename the class to OAccessible to account for the
new responsibilities, and adjust its doc accordingly.

Renaming source and header file will be done in a
separate commit to simplify (git) keeping track.
