* Implement query to check if texture format is mipmappable
This will allow Filament's users to perform check beforehand.
* add java bindings
* add javascript binding
the new MaterialInstance::setCullingMode(color, shadow) API allows to
set a separate face culling mode for the color pass and the shadow
passes.
FIXES[391679058]
* validate MaterialInstance references when destroyed
With this change we now enforce two things:
- All MaterialInstance of a Material must be destroyed when
destroying said Material. This has always been a documented
requirement of the public API, but wasn't enforced (only
a warning was printed).
This new assertion is unconditional.
- A MaterialInstance, when destroyed is no longer in use by any
Renderable.
So before destroying a MaterialInstance, the user of API needs to
ensure that either all Renderable using that MaterialInstance in one
of their Render Primitives are destroyed, or, that these Renderable
using that MaterialInstance are reset to another one or to null.
There is a new RenderableManager::clearMaterialInstanceAt() that can
be used to clear a MaterialInstance on a Render Primitive.
Additionally, a Render Primitive with a null MaterialInstance is now
silently skipped during rendering, instead of a null-dereference.
Finally, that second assert is protected by a new feature flag:
"features.engine.debug.assert_material_instance_in_use". This flag is
enabled on DEBUG builds and disabled on RELEASE builds by default.
The flag can be changed at any time using `Engine::setFeatureFlag()`.

Add Renderer::skipFrame() which should be called when intentionally
skipping frames, for instance because the screen content hasn't changed,
allowing Filament to performance needed periodic tasks, such as
cache garbage collection and callback dispatches.
We also improve the ResourceAllocator cache eviction policy:
- the cache is aggressively purged when skipping a frame
- we aggressively evict entries older than 3 frames
The default Config is now set to a more agressive setting.
The ResourceAllocator used to be global and owned by the Engine, this
was causing some issues when using several Renderers because each
one could cause the eviction of cache data for another.
We now have a ResourceAllocator per Renderer, which makes more sense
because most resources are allocated by the FrameGraph.
We also introduce a ResourceAllocatorDisposer class, which is used
for checking in and out a texture from the cache, and destroy the
texture when it's checked-out. That objet is still global.
* don't crash if we don't have a Camera set on View
- also add a method to query if a camera was set
* Update android/filament-android/src/main/java/com/google/android/filament/View.java
