Don't suspend cache invalidation when running term splitting batch routine.

Browse Source 
`wp_suspend_cache_invalidation()` was originally added to increase performance,
but the switch to batch processing in [33615] mitigates serious performance
concerns.

As a precaution against timeouts, the batch size has been reduced from 20 to 10.

Props Chouby.
See #30261.
