TSL-MT and/or SyGuS doesnt support EUF

[santolucito]

test/regression/ModuloTheories/euf.tslmt doesn't generate any assumptions.

When I log the smt queries that are made (will push this logging feature soon), and try to run directly with cvc5 i get

(error "Parse Error: tmp/tmp_10.smt2:1.12: Illegal argument detected
void cvc5::internal::LogicInfo::setLogicString(std::string)

  `logicString' is a bad argument
LogicInfo::setLogicString(): cannot parse logic string: EUF")

At least need to be throwing a warning to this effect in the toolchain, ideally we can actually fix it too lol

its not clear to me that EUF in fact is or ever was a thing in CVC5. https://smtlib.cs.uiowa.edu/logics.shtml

I think we just can use UF, or even better QF_UF
