QA: cannot create view with COALESCE(table.*) expression

From [star expressions in view definitions QA](https://gist.github.com/msirek/f8a9d1515244043088ec44d00accbe99),

The following view with a star expression in COALESCE works on Postgres, but not on CRDB:
```sql
CREATE TABLE strings (a text, b text, c text, d text);
CREATE OR REPLACE VIEW stars (star_cols) AS SELECT COALESCE(strings.*) AS star_cols FROM strings;
ERROR: cannot use anonymous record type as table column
SQLSTATE: 42P16
```

Jira issue: CRDB-25651

Reproduce the CREATE TABLE and CREATE OR REPLACE VIEW statements from the issue in CockroachDB and PostgreSQL, then trace the view-definition handling for COALESCE(strings.*). Done means the CockroachDB statement succeeds with the expected view column behavior and relevant SQL tests pass.
