Switch css::accessibility::AccessibleRelationType
from integer constants to an enum.
This provides more type safety and improves the debugging
experience, e.g. GDB now prints
com::sun:⭐:accessibility::AccessibleRelationType::AccessibleRelationType_CONTENT_FLOWS_TO
instead of just "2" when printing the value of a
corresponding variable, so it's no longer necessary
to manually look up what constant has that integer
value to know what relation this refers to.

However, the a11y UNO API is internal (not published),
so that shouldn't be a concern.
