Summary:
Noticed a couple bugs here, around a crash from assertion internal to the caching map which hashes on the AttributedString, that may or may not be related.

  1. We are missing baseTextAttributes for both hashing and equality (which is mostly innocuous, but still wrong)
  2. We were not hashing or comparing textAlignVertical
  3. For equality, we were comparing parent shadow view tag and metrics, but for hashing, we were hashing the whole ShadowView.

I think #3 could cause issues, since we could see different hash despite equality, which could break invariants.

Noticed a couple bugs here, around a crash from assertion internal to the caching map which hashes on the AttributedString, that may or may not be related.

1. We are missing `baseTextAttributes` for both hashing and equality (which is mostly innocuous, but still wrong)
2. We were not hashing or comparing `textAlignVertical`
3. For equality, we were comparing parent shadow view tag and metrics, but for hashing, we were hashing the whole ShadowView.

I think microsoft#3 could cause issues, since we could see different hash despite equality, which could break invariants.
