tdf#159910 a11y: Distinguish a11y name and text of toolbar item

So far, the accessible name and the text of the item
were considered to be the same, and fallbacks to still
get something else for the accessible name in case
of no item text (to use the quick help text or the item
window's accessible name instead) were implemented directly in
`VCLXAccessibleToolBoxItem::implGetText`.

However, `VCLXAccessibleToolBoxItem::implGetText` is also
used by the implementations for the methods from the
`XAccessibleText` interface and that one is clearly about
text displayed on screen, so using e.g. the quick help/tooltip
text doesn't make sense then.

Let `VCLXAccessibleToolBoxItem::implGetText` only handle the
actual item text and move the fallbacks to a new helper
method `VCLXAccessibleToolBoxItem::implGetAccessibleName`
instead that is only used when the actual accessible name
is wanted.
