(cloud-merge) Support shadow tablet to do cumulative compaction in cl…

…oud mode (apache#37293)

In cloud mode, when do schema change, shadow tablet encounters -235
because it cant do cumulative compaction in the case of a large number
of loads. And it will prevents the user from continuing to loads.
Implementation details:
1. When start schema change, record the end convert rowset version
`alter_version` into SchemaChangeJob.
2. For origin tablet, only can do base compaction in [0,
`alter_version`] and do cumulative compaction in (`alter_version`, N].
can not do compaction across `alter_verison` such as compaction [a,
`alter_version` + n].
3. For shadow tablet, cannot do base compaction and and do cumulative
compaction in (`alter_version`, N].
4. When the schema change failed because FE or BE coredump, it will
retry. When retry the schema change, it will get the `alter_version`
from meta_serive, and continue to do it.
5. When finish the schema change job or cancel it, we need to clear the
schema change job. Before this pr, it will cover by next schema change.
