[BugenZhao]

I hereby agree to the terms of the Singularity Data, Inc. Contributor License Agreement.

What's changed and what's your intention?

As explained in #5728. This PR introduces (back, #122) the state of the table fragments. Currently, it has Creating as the initial value and Created after the mview is completely created (command "finish"es). For those fragments with Creating as the table fragments state, we'll throw an error if asked to scale.

Checklist

• I have written necessary rustdoc comments
• I have added necessary unit tests and integration tests
• All checks passed in ./risedev check (or alias, ./risedev c)

Refer to a related PR or issue link (optional)

• Close Ban scaling of "MV on MV" being created by introducing the table fragments state #5729
