schemeshard: fix split key selection from access sample (#18201)

Fix crash when selecting split key from key access sample containing entries of different sizes. Size differences could occur when exact key accesses are mixed with key prefix operations (such as range reads). But the key comparator used was asymmetrical, allowing comparison of full keys to prefixes but not vice versa.
