Feature gate permissioned signer

[runtian-zhou]

Description

Adds support for permissioned signer functionality in the Aptos framework by introducing a new feature flag PERMISSIONED_SIGNER. This change enables controlled access to signer capabilities through permission checks. The implementation includes feature flag assertions in the permissioned signer module to ensure the feature is enabled before use.

How Has This Been Tested?

The feature flag implementation follows established patterns used for other feature flags in the system. Testing is enforced through the existing feature flag testing infrastructure.

Key Areas to Review

• Feature flag integration in permissioned_signer.move
• New permission checks added to signer_from_permissioned_handle and signer_from_storable_permissioned_handle
• Feature flag constant definition and helper functions in features.move

Type of Change

• New feature
• Aptos Framework
