[PATCH] lisp/org.el: Obsolete `org-cached-entry-get' in favor of `org-entry-get'

[Morgan Smith <Morgan.J.Smith@outlook.com>]

* lisp/org.el (org-cached-entry-get): Rewrite in terms
`org-entry-get'.  Obsolete in favor of `org-entry-get'.
(org-make-tags-matcher): Replace uses of `org-cached-entry-get' with
`org-entry-get'.
---
Hello!

All tests pass.

I don't think we can justify the existence of this function but let me know if
I'm wrong.

The caching mechanism used here is likely to cause hard to diagnose issues.

All of the logic here already exists in `org-entry-get'.

This function is mentioned in very few commits unlike its more popular sibling.

Thanks,

Morgan
