core/state, trie: remove Try prefix in Trie accessors (#26975)

Browse Source 
This change renames StateTrie methods to remove the Try* prefix. 

We added the Trie methods with prefix 'Try' a long time ago, working
around the problem that most existing methods of Trie did not return the
database error. This weird naming convention has persisted until now.
