test(language-service): remove MockData from MockTypescriptHost (#32752)

Browse Source 
Remove MockData from the constructor parameters of MockTypescriptHost
since the entire Tour of Heroes (TOH) project is now loaded from disk.

Added a new method `reset()` to MockTypescriptHost that is necessary to
reset the state of the project before each spec if run to make sure
previous overrides are cleared.
