Enable continuous backup for AllVersionsAndDeletes change feed tests

Add enableContinuousBackup parameter to test-resources.bicep to configure
continuous backup policy when needed. Add a new account configuration in
live-platform-matrix.json for AllVersionsAndDeletes change feed tests that
enables continuous backup.

This fixes the live tests for PR #4706 that require continuous backup to
be enabled for the AllVersionsAndDeletes change feed mode to function properly.
