### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #37396
Problem Summary:
`test_create_mv_and_mtmv` verifies that an async MTMV can read a sync rollup
MV, resolve the rollup column back to the base-table partition column, and
complete full and partial refreshes.
The original case disabled cost-based sync MV selection so both the
precondition query and MTMV definition actually read the sync rollup. After
that control was removed, `TRY_IN_RBO` could successfully generate the rollup
candidate while cost-based planning still selected the base index, causing an
intermittent `MaterializedViewRewriteSuccessButNotChose` failure before MTMV
creation.
Add `USE_MV` to both queries so the case deterministically exercises the
intended sync-rollup path while retaining the existing full and partial refresh
assertions.
