Message:

Improve 'offset' calculation when querying for hierarchical terms.

When querying for terms in hierarchical taxonomies, get_terms() initially
queries for all matching terms, and then trims the located results based on the
$number and $offset arguments passed to the function. See #8832. However,
a flaw in the original logic meant that results were failing to be trimmed
properly in cases where $offset exceeds the total number of matching terms;
in these cases, we should force an empty array.

Props danielbachhuber.
Fixes #35935.
