3DTiles spamming console.log with thousands of messages.

[mramato]

#4228 added a message about using the old 3DTiles b3dm format, but it's using console.log and spamming the output with thousands of messages when working with most existing 3DTiles sets. It should use oneTimeWarning or depracationWarning instead.

Agreed, this is commented out in the 3d-tiles-temp branch, but do not use that branch right now as it is experimental.

@JudyWeng let's do this one next. Use a deprecationWarning, for example like 72c7f4a#diff-5616be61ebe4c0b247de93dde619a130L295

For testing you can follow the same steps as here: #3892 (comment). You can also use the same tileset for testing since it is in the legacy format.
