Improve CQL Injection Query

[jeongsoolee09]

What this PR contributes

• Improve CQL Injection Query.
  • Expand base objects as possible receivers of methods .run and property read entities:
    • EntityEntry now includes property reads from srv.entities, e.g. const { Entity } = srv.entities.
    • A new class CqlQueryRunnerCall now expands and replaces TaintedCqlClause, now covering cds.run, cds.db.run, srv.run.
• Add robust test cases.
  • Service1, when receiving event send11 through send15, runs query on the database service using cds.run.
  • Service1, when receiving event send21 through send25, runs query on itself by await-ing the query.
  • Service1, when receiving event send31 through send35, runs query on Service2 by srv.run where srv is an instance of Service2.
