lock_rider_rotation doesn't work, glitches hand

Partner Rank: 2

Verification builds: 1.13.0.1, 1.13.0.2
Regression builds: 1.12.25.0

Summary: lock_rider_rotation only works for boats now, on other entities it glitches the player's hand/targeted block around, but does not prevent rotating.

Impact: This prevents a small mechanic in an upcoming map.

Repro Steps:

1. Download and open the attached world
2. Ride the boat and try to spin back and forth
3. Ride the pig and try to spin back and forth

Expected Results: Since the pig behavior is a copy/paste of boat behavior, it too should stop you from rotating too far.

Observed Results: It doesn't. Instead, it makes the player's hand flicker slightly and makes the targeted block change rapidly.

Screenshots/Videos attached: No

Notes: I also believe rotate_rider_by has never worked for non-vanilla mobs in any version. I'll create a new ticket for this if necessary.
