### Is your feature request related to a problem or challenge?
`DataFrame` exposes `select_columns` and `select` methods. The first of
which expects list of columns to be selected, later one expects list of
expressions created using logical expression API , which is straight forward
but still needs some effort.
### Describe the solution you'd like
With `parse_sql_expr` available, it may make sense to provide `select_expr`
which would accept list of expressions as strings, and convert them to actual
logical expressions.
Something similar to:
```rust
pub fn select_expr(self, exprs: &[&str]) -> Result<DataFrame> {
let expr_list = exprs
.iter()
.map(|e| self.parse_sql_expr(e))
.collect::<Result<Vec<_>>>()?;
self.select(expr_list)
}
```
This would be equivalent to spark dataframe `selectExp`

### Describe alternatives you've considered
_No response_
### Additional context
https://github.com/apache/datafusion/issues/12518 looks like there is issue
with `parse_sql_expr` and alias handling
