Move Lock View Rotation label logic out of process notification

[ryevdokimov]

Requires and Includes: #109469

There is no reason to update this every frame.

Tested locally, it works as expected (the update spinner no longer spins continuously when visible). Code looks good to me.

Rebased since #109469 was merged
