[SPARK-15029] improve error message for Generate
## What changes were proposed in this pull request?
This PR improve the error message for `Generate` in 3 cases:

2. generator appears more than one time in SELECT, e.g. `SELECT explode(list), explode(list) FROM tbl`
3. generator appears in other operator which is not project, e.g. `SELECT * FROM tbl SORT BY explode(list)`
## How was this patch tested?
new tests in `AnalysisErrorSuite`
