ResourceLoader creating too many jobs and crashes

⚠️ **Issues not using this template will be systematically closed.**

**Describe the bug**
ResourceLoader [creates](https://github.com/google/filament/blob/1c2ffc9ed4581080e53b23dda63ed7bfee6311e7/libs/gltfio/src/ResourceLoader.cpp#L743) a job for each primitive to compute tangent. This crashes filament when loading a larger model, even on Pixel 8 (which has been the best case device from our testing on various models).

Computing tangents for all primitives in a single job works (no longer crashes) but I guess that's not ideal, jobs can run in parallel ? So may we run them in batches to avoid creating way too many jobs?

**To Reproduce**
Steps to reproduce the behavior:
Load a model with 50+K renderables

**Expected behavior**
ResourceLoader#computeTangents shouldn't crash

**Logs**
