Better hints to set `enableDebugWireframe` in tileset constructor

[j9liu]

As of Cesium 1.97, the enableDebugWireframe flag will be required for debugWireframe to work, for both Model and Cesium3DTileset. Otherwise, nothing happens when debugWireframe is toggled. We should more clearly convey to the user that enableDebugWireframe needs to be set true for debugWireframe to work.

Some suggestions:

• oneTimeWarning if a user is setting debugWireframe: true in the tileset constructor without setting enableDebugWireframe true, or if a user is setting debugWireframe at runtime
• same for Model
• disabling the wireframe checkbox in Cesium3DTilesInspector, with some text that enableDebugWireframe should be true for this to work`

I can take a look into implementing this if nobody else has started working on it.

Thanks for your interest in contributing @Sn00pyW00dst0ck! I don't believe anyone has started working on it, so feel free to contribute and open a PR when you're able 😀

Looks like this was addressed by #10803, so I'm closing this issue.
