Snowflake LIST @foo and REMOVE @foo stage syntax fail to parse with a semicolon

```sql
-- breaks
LIST @bar;

-- ok
LIST @bar

-- breaks
REMOVE @bar;

-- ok
REMOVE @bar
```

This is starting to become a theme. See #1244, #1519.

1. can all the tests be made to test both with and without a semicolon
2. can the parser be generalized so whether a statement ends with EOF or `;` isn't up to every individual statement

先找出 parser 的進入點以及 LIST 和 REMOVE 的現有測試，然後比較此處描述的有分號和無分號情況。完成的標準是兩種形式都能一致地進行解析，相關測試涵蓋兩種結尾，且陳述式終止不再由每個陳述式分別處理。
