Ivan Butygin 15e915a44f [mlir][dataflow] Propagate errors from visitOperation (#105448) ...

Base `DataFlowAnalysis::visit` returns `LogicalResult`, but wrappers's
Sparse/Dense/Forward/Backward `visitOperation` doesn't.

Sometimes it's needed to abort solver early if some unrecoverable
condition detected inside analysis.

Update `visitOperation` to return `LogicalResult` and propagate it to
`solver.initializeAndRun()`. Only `visitOperation` is updated for now,
it's possible to update other hooks like `visitNonControlFlowArguments`,
bit it's not needed immediately and let's keep this PR small.

Hijacked `UnderlyingValueAnalysis` test analysis to test it.
