Building time increases when Optimize Mesh Data is enabled
How to reproduce:
1. Open the attached project "1349093-repro.zip" with Windows set as Target Platform
2. In File > Build Settings, make sure that Scenes/SampleScene is added to Scenes In Build
3. Build and observe how long it took for the build to complete in the Console tab
4. Go to Edit > Project Settings > Player > Other Settings > Optimization
5. Enable "Optimize Mesh Data"
6. Build the project again
Expected results: the second build completes in the same time or faster as was observed in step 3 (~30s)
Actual results: the second build takes much longer to complete (~400s)
Reproducible with: 2019.4.29f1, 2020.3.16f1, 2021.1.17f1, 2021.2.0b7, 2022.1.0a5
Notes:
- Increased build times were also observed when building for Nintendo Switch
- The very first build might take longer despite "Optimize Mesh Data" being disabled due to shader compilation

This doesn't happen in 2020.1.17 so whatever you added in the LTS regressed optimize mesh in a huge way
