[CompilationPipeline] Project recompile and package changes takes a long time when Project includes a lot of packages
Reproduction steps:
1. Open the user's attached project, or add attached "manifest.json" file to an empty project
2. Open Window > Analysis > Editor Iteration Profiler
3. Select "Enable" in Editor Iteration Profiler
4. Open Window > Analysis > Compilation Timeline
5. Press "Recompile", this just does a full recompile using CompilationPipeline.RequestScriptCompilation API
Expected result: Recompilation takes less than a minute
Actual result: Logged recompilation takes around a minute after that Editor becomes unresponsive for ~3-4 minutes while maintaining extremely high CPU and RAM usage (~80-90%)
Reproducible with: 2019.4.9f1, 2020.1.4f1, 2020.2.0b1
Couldn't test with: 2018.4 (errors after downgrade)
Note:
1. Using attached "manifest-2019.4.json", Editor freezes upon launch, takes all RAM memory, and needs to be ended using Task Manager - this issue is reported separately as case 1273659
2. Repro project doesn't have any assets but includes a lot of Unity Packages

It also affects third party packages.
Very slow, Import a package like peek takes 40 mins to finish.
