[sprout] Add shared runtime, improve error reporting

--- 

I added ~20 more tests to Sprout to get more of a feel for what the test 
framework would need to support all fixtures. I'm relatively confident that the 
approach outlined in [the original workplace 
post](https://fburl.com/workplace/ftu8woch) works to migrate almost all existing 
fixture tests to sprout (TLDR: use shared functions when possible, otherwise 
write helper functions in-file). 

Add `shared-runtime` file to reduce the amount of overhead needed to set up a 
fixture test. 

- All generalizable functions and values should be added here (e.g. 
`shallowCopy`, `deepCopy`, `sum`). 

- Editor integration is set up through a custom tsconfig, so importing from 
`shared-runtime` should just work (with hover annotations, click-to-definition, 
etc).

Tested new test fixtures added to sprout by adding them to `testfilter.txt` and 
running with `--verbose --filter`. 

Note that there are no unexpected exceptions, and all logs + returned values 
match.
