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

首先定位 parser 的入口点以及 LIST 和 REMOVE 的现有测试，然后比较此处描述的带分号和不带分号的情况。完成的标准是两种形式都能一致地进行解析，相关测试覆盖两种结尾，并且语句终止不再由每条语句分别处理。
