a11y: Move CharacterAttributeshelper from accessibility to vcl

This is in preparation of moving more from
the accessibility module to vcl.

Currently, the a11y implementations for vcl widgets
are implemented in the accessibility module (in
directory of the same name), which in turn depends
on the toolkit module.
To break the dependency cycle (vcl needs accessibility
to create a11y objects for its widgets), there's a UNO
service.

At least some a11y classes don't really need toolkit,
however, so the plan is to decouple this and move those
from the accessibility module into vcl in upcoming
commits.
