### What changes were proposed in this pull request?
With ANSI mode, `SELECT make_timestamp(1, 1, 1, 1, 1, 1)` fails, because the 'seconds' parameter needs to be of type DECIMAL(8,6), and INT can't be implicitly casted to DECIMAL(8,6) under ANSI mode.
```
org.apache.spark.sql.AnalysisException
cannot resolve 'make_timestamp(1, 1, 1, 1, 1, 1)' due to data type mismatch: argument 6 requires decimal(8,6) type, however, '1' is of int type.; line 1 pos 7
```
We should update the function `make_timestamp` to allow integer type 'seconds' parameter.
### Why are the changes needed?
Make `make_timestamp` could accepts integer as 'seconds' parameter.
### Does this PR introduce _any_ user-facing change?
'Yes'.
`make_timestamp` could accepts integer as 'seconds' parameter.
### How was this patch tested?
New tests.
Closes#33665 from beliefer/SPARK-36428.
