AuditLog: Align the implementation to the PSA header
This change modifies the AuditLog service implementation
to reflect the changes introduced by the PSA compliant API
interface. The symbol name patterns for functions, variables,
folders and source files are also changed to be audit_* /
tfm_audit*.
