TapLoader: improve load logic

Browse Source 
* Use `Tap#formula_dir` instead of `Tap#formula_files` to find formula
  file to have better performance and avoid caching issue.
* Change the loader logic to search name -> search alias -> search old name.
  This is more consistence with what we do when loading core formula
  file.

Closes Homebrew/homebrew#49484.
