tdf#157088 a11y: Dispose list items with list
Don't only clear, but also dispose the
list items when the `VCLXAccessibleList`
gets disposed.
Interestingly, there was already a comment
saying
// Dispose all items in the list.
, but that wasn't done so far...
Fixes a crash on exit with the below backtrace
after using the font color toolbox item with
the qt6 VCL plugin and Orca running:
