Improve server performance by decreasing the number of Analysis context's created #53874
Description
We have seen the analysis server consume large memory such that it is rendered unusable.
#52447
#41793
Reducing the number of AnalysisContext's creates and used when analyzing user code will result in improvement of performance and memory usage.
Two arcs of work have been identified as a way to reduce the number of contexts
- support a monorepo workspace, based on changes to pub proposal #4022
- Support multi-option contexts #53876
- move strictCasts bool field out of TypeSystemImpl analyzer: move strictCasts bool field out of TypeSystemImpl #53873
