Update thirdparty/meshoptimizer with distance-only error metric This change replicates the distance-only metric patch which is now much smaller and cleaner, as upstream simplifier already tracks distance and attribute quadrics separately - it just doesn't store both errors in the collapse structures. The old two patches were removed as they are no longer needed.

Update meshoptimizer to 0.22 The Godot-specific patch is just a single line now; removing this patch will likely require adjusting Godot importer code to handle error limits better. This also adds new SIMPLIFY_ options; Godot is currently not using any of these but might use SIMPLIFY_PRUNE and SIMPLIFY_SPARSE in the future.
