if collecting of the placed symbols data is enabled, returns the reference to the `PlacedSymbolData` vector holding the collected data.

### 🐞 Bug fixes

- [core][tile mode] Reduce cut-off labels (part 2) ([#16369](https://github.com/mapbox/mapbox-gl-native/pull/16369))

Now, the intersecting symbols are placed across all layers _symbol by symbol_ according to the following rules:

1. First we look, which of the tile border(s) the symbol intersects and prioritize the the symbol placement accordingly (high priority -> low priority): `vertical & horizontal -> vertical -> horizontal`
2. For the symbols that intersect the same tile border(s), assuming the tile border split symbol into several sections, we look at the minimal section length. The symbol with a larger minimal section length is placed first.
3. For the symbols that intersect the same tile border(s), and have equal minimal section length, we look at the anchor coordinates.
4. Finally, if all the previous criteria are the same, we look at the symbol key hashes.

- [core][tile mode] Fix variable placement for labels with the `icon-text-fit` property set ([#16382](https://github.com/mapbox/mapbox-gl-native/pull/16382))

The `symbolIntersectsTileEdges()` util in `mbgl::TilePlacement` now considers icon shift for the variable symbols with enabled icon-text-fit setting, thus providing more accurate results.

When dem tiles are loaded, border in neighboring tiles is updated, too leading to bucket re-upload. if std::move moved indices / vertices previously, they are empty and we get crash. Re-upload requires that only DEM texture is re-uploaded, not the quad vertices and indices.
