refactor: rename util to lazy injection token

[davidlj95]

Issue or need

After giving a try to apply the recently created (in #892) function to create lazy injection tokens, found out a repeating pattern.

(Lazy) tokens were being declared as:

const token = () => _makeInjectionToken('desc', factory)

The () => part could actually be part of the util. Given will always be like that in order to allow tree shaking injection tokens.

Actually the util could be as is + then create another one _lazy that uses _make under the hood.

Buuut the logic of lazyness is in the _make one (not creating 2 tokens if one exists). Soo makes sense that for now it's just one API.

It's internal, so can be decomposed later if needed.

Proposed changes

Rename util to _lazyInjectionToken as it will now return lazy injection tokens.

Add a type to specify what actually a _LazyInjectionToken is. Plus some docs.

Fix tests
