feat(core): support sharing one redb database between different Operators

[TD-Sky]

Which issue does this PR close?

Closes #6172 .

What changes are included in this PR?

• RedbBuilder::database(self, db: &Arc<redb::Database>) -> Self
• Creating the specified table at build stage if it doesn't exist (It's really important because trying to get something in table is a common need, but errors will occur when the table doesn't exist)

Are there any user-facing changes?

• Users got a new method: opendal::services::Redb::database(self, db: &Arc<redb::Database>) -> Self
• (breaking change) OperatorInfo::name for redb become table name instead of datadir.
