Taxonomy: Remove placeholder from WP_Term_Query cache key.

Browse Source 
Remove escape placeholder from query cache key, as placeholders are on a based on a unique id on every request. This meant that it is impossible for a cache to be reused, making queries that use escape placeholders such as searches, meta queries or using the `description__like` / `name__like` parameters were unable to be cached.  
 
Follow on from [54634]. 

Props spacedmonkey, peterwilsoncc.
Fixes #57298.
