8327651: Rename DictionaryEntry members related to protection domain

[iklam]

Rename DictionaryEntry::_pd_set to _package_access_cache, and rename all related methods accordingly.

The old name was very confusing. It makes one wonder,

Is DictionaryEntry::_pd_set related to the java.lang.Class.getProtectionDomain() of the DictionaryEntry::_instance_klass in any way?

(Hint, they have absolutely no relationship to each other).

I am making this PR as future changes in the Leyden project may be touching this area. I don't want the reviewers of my future PRs be confused by this code.
