Add `"WebGL"` to unit tests

1

This PR adds the missing `"WebGL"` keyword to various `ModelExperimental` specs for consistency with the rest of Cesium's unit tests.

Setting `model.style` before the `readyPromise` is resolved leads to this error:  This is because the `style` setter doesn't check if the model has loaded or not, so it's trying...

Handle `skipLevelOfDetail` and backface commands in `ModelFeatureTable`

2

`Cesium3DTileBatchTable` has code for handling `tileset._skipLevelOfDetail`, which determines whether backface commands are generated for tiles in the tileset. The equivalent class in `ModelExperimental` `ModelFeatureTable`, does not handle this yet. When...

Better hints to set `enableDebugWireframe` in tileset constructor

3

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...

Update `IndexDatatype.createTypedArray` to create Uint8Arrays

4

Currently `IndexDatatype.createTypedArray` only outputs `Uint16Array` and `Uint32Array`. This caused a bug in #10344 because it returned a `Uint16Array` for uint8 indices, which was too big for the `getBufferData` function. The...
