Description

LUCENE-9028 added a `multiterm` factory method for intervals that accepts an arbitrary Automaton, and converts it internally into a CompiledAutomaton.  This isn't necessarily correct behaviour, however, because Automatons can be defined in both binary and unicode space, and there's no way of telling which it is when it comes to compiling them.  In particular, for automatons produced by FuzzyTermsEnum, we need to convert them to unicode before compilation.

The `multiterm` factory should just take `CompiledAutomaton` directly, and we should deprecate the methods that take `Automaton` and remove in master.
