Native version of mapbox/mapbox-gl-js#6548.
Port of mapbox/mapbox-gl-js#6550.
Prevents symbols that share the same layout properties from colliding against each other.
Bump GL JS pin to get regression test.
Rename "bucketName" -> "bucketLeaderID" to make it clearer what it represents.
Port of GL JS PR #5994.
Fixes issue #10844, which would allow multiple symbols in a tile to share the same crossTileID as one of their duplicate parent-tile symbols. Once the symbols shared a crossTileID, they would permanently remain "duplicates" of each other, even after increasing zoom level allowed the CrossTileSymbolIndex to distinguish between them.
