[chore](backup) Fix the db name of the restored view (#38072)

Browse Source 
Cherry-pick #37412, #39855

Previously, during restore, the database name in the CREATE VIEW
statement was not modified, causing the restored view to be unviewable
with the SHOW VIEW command. This PR retains the original cluster's
database name in the BackupMeta and manually replaces it with the new
cluster's database name in the CREATE VIEW statement during restore.
