[fix](group commit) fix repaly wal check label status (#38883)
## Proposed changes
When replay wal, it firstly abort the txn with the label but does not
check the abort result.
And when begin txn of replay, if FE returns `LabelAlreadyUsedException`,
it consider the load is success in previous group commit load or repaly
wal, and delete this wal directly.
But `LabelAlreadyUsedException` means there is a txn with this label,
the txn may be in `PREPARE / RUNNING / COMMITTED / VISIBLE` status(the
abort txn in first step may fail), so replay wal should check both
`LabelAlreadyUsedException` and txn status is `COMMITTED / VISIBLE`.
This pr also add a case for replay wal with schema change.
