Could just call startCachingPerDirectoryResolution from here?

Should an exception during program update be recoverable? Might it be more useful to crash tsserver if we throw during program update and don't catch until the event loop?

Nit: Would prefer program && changesAffectModuleResolution(program.getCompilerOptions(), compilerOptions) since if !program, changesAffectModuleResolution has nothing it can do.

Would be nice to have #8306 so we didn't need to include this..

Handle the case when finishCachingPerDirectoryResolution is not called because of exception
Fixes #18975
Assert if the script info that is attached to closed project is present. This also releases external project files that get attached to the project when project is closed
Handle project close to release all the script infos held by the project. Above assert revealed that if the project update was pending and project is closed, the files added as root but not yet in program (because the project's update graph was pending/delayed) wont be released and hence those script infos holding onto the closed project.
Fixes #19003 and #18928
