Show tooltips on hover for type property definitions and type additional properties accesses

[jeskew]

Resolves #13461
Resolves #13398

There were a couple of scenarios where the LS was not showing hover tooltips for properties:

• When hovering over a type property definition
• When hovering over a property name that would match against a value's additional properties type

There's no way to capture a description for an object's additional properties type, but the hover can at least show the expected type.
