Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Tested on the latest datafusion-cli

❯ select count(2.2);
+-----------------+
| COUNT(UInt8(1)) |
+-----------------+
| 1               |
+-----------------+

Expected behavior
I'd like the column name to be

COUNT(Float64(2.2))

Additional context
Add any other context about the problem here.

Hi @andygrove, I guess this bug is probably related to the sql-parser. Because there is no error when constructing the expression directly:

    #[test]
    fn my_test() -> Result<()> {
        let expr = count(lit(2.2));
        let expected = "COUNT(Float64(2.2))";
        assert_eq!(expected, expr.display_name()?);
        Ok(())
    }

There is a hardcoded value in COUNT_STAR_EXPANSION that expands to pub const COUNT_STAR_EXPANSION: ScalarValue = ScalarValue::UInt8(Some(1));, @andygrove should we fixed this as above?
