Read a star's REPLACE and ILIKE

[IL-William]

Patch 10 of the engine fork that collin pins (dbt-collin decision 0028). A star's REPLACE and ILIKE are now read when the star is expanded, as its EXCLUDE, EXCEPT and RENAME already were.

Until now the star expanded every column as it was:

• SELECT * REPLACE (UPPER(b) AS b) FROM p came out with b a copy of p.b;
• SELECT * ILIKE 'a%' FROM p came out with a, b and c.

The change

• REPLACE: a column it names takes the replacing expression in its place, under its own name. It reads what the expression reads, and keeps the expression.
• ILIKE: keeps only the columns whose name the pattern matches, as SQL's LIKE does (% for any run, _ for any one character), without regard to case.

Tests

• ILIKE: a prefix, a suffix, a single-character pattern, a qualified star, a pattern in another case, and a CTE read through.
• REPLACE: replacing with an expression of the column itself, of another column, and inside a CTE.
• Both fail without the patch. 2964 tests pass, and cargo fmt --check is clean.

Measured through collin

Project	Effect
3507 model Snowflake project, both its compiles	cache identical, --indirect too: no model uses either option
Cal-ITP, Shopify	identical
lineage-library	book_labels.title is now a transform of books.title, and loan_keys keeps its three _id columns and is parsed: the three marks for these limits go

Nothing goes to pondpilot/flowscope.
