Merge the v1.57.0 release-branch changes back to main (cherry-picked onto main) and open the next 1.58.0 (TBD).

• Prepare release v1.57.0 (version bump, dated CHANGELOG, AST test data)
• NO-SNOW: fix debug source positions when snowpark is imported through a symlink #4502 symlink debug-position fix (cherry-picked to the release branch; its own PR to main is still open, so it can be closed after this merges)
• NO-SNOW: fix daily precommit test failures #4498 was already on main and was skipped

Review the CHANGELOG reconcile.
