This is nearly all of the remaining DTA/TDA changes in #24024. The things that are not included:
value_countsfrom 24024 has small change to make sure the tz-aware case is correct regardless of how the constructor changes in 24024 get resolved. A test is added specifically to check for this.The changes implied by mixing ExtensionArray into DatetimeLikeArrayMixin are not tested yet, won't be until the extension tests part of #24024 is merged. I don't see any way around that except for doing 24024 all at once.
