feat(repl): allow using "type" command on types/interfaces

[ejose19]

This makes "type" command return a more accurate description than the currently any for types/interfaces. It's worth noting that until microsoft/TypeScript#25894 is fixed, interfaces/enums will be shown as just "$kind $identifier".

Based on https://stackoverflow.com/a/55777714.

Regarding the undefined as unknown as ${identifier}, it's required due #1126 (#1126 (comment)), so it's done this way to avoid having errors in subsequent commands.

Had to split the type tests into 2 due to the current linked issue, as getQuickInfoAtPosition is using an invalid position after the first type call.
