100% CPU usage for an extended period of time when importing an asset with a lot of 4096x4096 texture files
How to reproduce:
1. Create a new project
2. Import "ELEMENTAL DRAGONS PACK" from the Asset Store
Expected result: Asset is imported at the speed and the CPU usage compared to the similar size and type assets
Actual result: Asset is being imported for an extended period of time using 100% of the CPU
Reproducible with (5-10 minutes of 100% CPU) - 2018.4.29f1, 2019.4.15f1, 2020.2.1f1, 2021.1.0a10
CPU used to test: Intel(R) Xeon(R) W-2145 CPU @ 3.70GHz (16 CPUs), 3.70GHz

The solution I implemented was to simply manually scale down the many 65mb textures as they were mostly roughness and metallic textures down to 2k instead of 4k which dramatically changed their filesize down to 12mb and that helped import times a lot faster.

This issue has not been resolved. Exact same problem happened in the latest Unity 2021.4 It ultimately crashed Unity after getting through to 75^ of the way with the entire time having 100% Cpu once again clearly because of the dragons pack.
