  1. Improve performance by caching find_spec 

    Certain checkers upstream on pylint like import-error heavily use
find_spec. This method is IO intensive as it looks for files
across several search paths to return a ModuleSpec.

Since imports across files may repeat themselves it makes sense to cache
this method in order to speed up the linting process.

Closes pylint-dev/pylint#9310.

  2. Remove AstroidCacheSetupMixin 

    This class predates efforts to have a central interface to control
global state (including caches) and it is no longer needed.
