Subject: [PATCH] Implement chip::Access::AccessControl::ResetAccessControl
 (#23416)

* Implement chip::Access::AccessControl::ResetAccessControl

It is not currently possible to release the injected AccessControl
instance from the sdk's Access control singleton vendor because the
symmetric reset method for Access::SetAccessControl isn't implemented.
This commit adds the implementation.

Fixes #23415

* Per Andrei Litvin, s/ResetAccessControl/ResetAccessControlToDefault
