Disable tests that require an extension

[shehzan10]

The following tests are skipped:

• Scene/Primitive renders with distance display condition per instance attribute (floatingPointTextures)
• Scene/GroundPrimitive renders with distance display condition per instance attribute (floatingPointTextures)
• Scene/BillboardCollection renders more than 16k billboards (instancedArray)
• Renderer/Context get the frame depth extension (frameDepth)

Fixes #4711 along with #4980.

According to @bagnell the primitive, ground primitive, billboard collection tests should be fixed in the backend to have proper fallback. I can open a new issue for that.

I agree that the workaround in the test is not the right place. What do you mean by "backend?" The implementation, right?

I'm not sure that we can prioritize those right now. Perhaps update #4711 with the new info and trim this down to just the Renderer/Context get the frame depth extension fix which is correct.

Merging this PR and (#4980) would make #4711 failures go away. I am not seeing any more of those.

Yes, by backend I mean implementation. The proper fallback fix in the implementation can be done later (for which we can create an issue).

Are you sure this is instancing, not the uint32 extension?

Yes, the test passes when I explicitly set the elementIndexUint extension to false.

See #4988

So do you want me to keep the if(extension) conditions as a part of this PR?

Yes, I think it is OK given the issue written.
