Add definitionContainers to categories tree

closes #1126

Impressive set of tests - great work!

[saskliutas]

I don't see where idsCacheRef.current is reset when view type or iModel changes so it will always return same cache.

[JonasDov]

Yeah, missed that, removed the condition, changed to useMemo

I created a test iModel to check query performance and noticed some worrying things.

The code to create a test iModel:

await buildIModel(this, async (builder) => {
  const physicalModel = insertPhysicalModelWithPartition({ builder, codeValue: "TestPhysicalModel" });

  for (let i = 0; i < 1000; ++i) {
    const definitionContainer = insertDefinitionContainer({ builder, codeValue: `Definition container ${i + 1}` });
    const definitionModel = insertSubModel({ builder, classFullName: "BisCore.DefinitionModel", modeledElementId: definitionContainer.id });
    if (i === 0) {
      for (let j = 0; j < 1000; ++j) {
        const definitionContainerChild = insertDefinitionContainer({
          builder,
          codeValue: `Child definition container ${j + 1}`,
          modelId: definitionModel.id,
        });
        const definitionModelChild = insertSubModel({ builder, classFullName: "BisCore.DefinitionModel", modeledElementId: definitionContainerChild.id });
        const category = insertSpatialCategory({ builder, codeValue: "Child category", modelId: definitionModelChild.id });
        insertPhysicalElement({ builder, modelId: physicalModel.id, categoryId: category.id });
      }
    } else if (i === 1) {
      for (let j = 0; j < 1000; ++j) {
        const category = insertSpatialCategory({ builder, codeValue: `Child category ${j + 1}`, modelId: definitionModel.id });
        insertPhysicalElement({ builder, modelId: physicalModel.id, categoryId: category.id });
      }
    } else if (i % 2 === 0) {
      const definitionContainerChild = insertDefinitionContainer({ builder, codeValue: "Child definition container", modelId: definitionModel.id });
      const definitionModelChild = insertSubModel({ builder, classFullName: "BisCore.DefinitionModel", modeledElementId: definitionContainerChild.id });
      const category = insertSpatialCategory({ builder, codeValue: "Child category", modelId: definitionModelChild.id });
      insertPhysicalElement({ builder, modelId: physicalModel.id, categoryId: category.id });
    } else {
      const category = insertSpatialCategory({ builder, codeValue: "Child category", modelId: definitionModel.id });
      insertPhysicalElement({ builder, modelId: physicalModel.id, categoryId: category.id });
    }
  }
});

Observations:

1. Loading initial view takes ~4 seconds (our target is < 1 second).
2. When loading initial view, the following query is executed twice:

   SELECT ECInstanceId as id FROM BisCore.SpatialCategory WHERE ECInstanceId IN (SELECT DISTINCT Category.Id as id from BisCore.GeometricElement3d WHERE Category.Id IN (SELECT ECInstanceId from BisCore.SpatialCategory))

3. When loading initial view, the following query takes ~2.8 seconds:

   WITH RECURSIVE DefinitionContainers(ECInstanceId, ModelId) AS (
       SELECT dc.ECInstanceId, dc.Model.Id
       FROM BisCore.DefinitionContainer dc
       WHERE dc.ECInstanceId IN
