[MC-188497] AngerTime and AngryAt cannot be set on summon

The bug

Mobs can't be summoned with AngryAt; this immediately resets their AngerTime to 0.

How to reproduce

Spawn in any mob where you know its UUID
```
/summon pig ~ ~ ~ {UUID:[I;1,2,3,4]}
```

Summon a wolf

/summon wolf ~ ~ ~ {AngerTime:10000,AngryAt:[I;1,2,3,4]}

❌ The wolf is not angry on spawn

Using data get shows that its AngerTime has reverted to 0 and it is missing AngryAt altogether

Note that Endermen are unreliable candidates for testing this bug, as their behavior when manually setting anger tags is inconsistent with the other neutral mobs (MC-188506).

Confirmed in 1.16 Release Candidate 1.

Confirmed to still be a problem in 1.16.2.
The AngerTime tag is completely ignored when custom set for any neutral mob. Doesn't matter if it's spawned/summoned, has the data modified, or has specific UUID set to be angry at. Reverts back to zero.

Just looked into it - this can be fixed if gamerule universalAnger is set to true
