Performance increase for no-absolute-path #843

See my reply here for a detailed analysis on why I made this change: #803 (comment)

I remove the call to resolve() in no-absolute-path rule. That should make this rule faster when it is used as a standalone rule or with other rules that are not dependent on having to resolve file paths.

As I currently see no reason to have to call resolve() for this rule at all. However, I am new to the code, so I may be wrong. :)

importTypes helper performs resolve() - which does not look needed for the no-absolute-path rule.

Additionally, the absolute condition only seems like it was used for no-absolute-path.

Finally, all the tests continue to pass.
The old name seems wrong. Probably copied from no-extraneuous-dependencies

looks great in practice, but see my comments for a lower-impact refactor 😁 thanks for digging into this!

instead of removing this, could you export it and then import it in no-absolute-path?

also keep this here, needed for import/order AFAIK

so this is replaced with import { isAbsolute } from '../core/importType'

@benmosher I missed your comments. Do you still want to make the suggested refactoring or was it done in another PR/commit?

Sorry - been a bit busy due to holidays and other priorities - and somehow I completely missed your messages.
