Evaluate submit requirements in submittability checks

The autosubmitter only evaluated legacy submit records from label
functions and ignored Submit Requirements (SRs). Since Gerrit 3.6, SRs
are the standard way to define submittability. As a result, the plugin
attempted to merge changes that were not actually submittable when SRs
were unsatisfied.

This change checks submittability using
ChangeData.submitRequirementsIncludingLegacy() and verifies that each
requirement is fulfilled before proceeding. This aligns the plugin’s
behavior with Gerrit’s submittability model and prevents premature
submission attempts.
