[D] Separate built-in type-aliases from built-in types (#3965)

This commit separates built-in type-aliases (e.g. `size_t`, `string`) from built-in types (e.g. `int`, `float`) so that their identifiers aren't treated as reserved (they aren't, e.g. you can make your own `string`), and so that they can be highlighted separately.
