Properly configure TypeScript

The types of the language service are emitted to the `types` directory.
The base `tsconfig` is split off from the solution file. As a result the
`include` / `exclude` options are no longer needed. `declarationMap` is
enabled, so editors can use _Go to Source Definition_.
