[feat](job)Implementing Job in Nereids (apache#41391)
## Proposed changes The JOB's execution SQL is currently defined by an older CUP file, which causes some issues with lexical analysis in the new optimizer as it doesn't pass under the old optimizer. Since the JOB's underlying execution already uses the new optimizer, we're planning to fully migrate to ANTLR4 for consistency. (cherry picked from commit 334b473)
