[EngSys] add VS Code vitest settings for core packages (#31583)

The vtest VS code extension
(https://marketplace.visualstudio.com/items?itemName=vitest.explorer)
works well for unit tests but not so for other packages because most of
them does not run properly without dev-tool.

Deleting vitest config files for healthinsights-radiologyinsights-rest
because it hasn't been migrated to use vitest yet.
