fix(ivy): never use imported type references as values (#29111)

Browse Source 
ngtsc occasionally converts a type reference (such as the type of a
parameter in a constructor) to a value reference (argument to a
directiveInject call). TypeScript has a bad habit of sometimes removing
the import statement associated with this type reference, because it's a
type only import when it initially looks at the file.

A solution to this is to always add an import to refer to a type position
value that's imported, and not rely on the existing import.
