[FEATURE] Lock achievements after generating achievement schema

[Smealm]

Prerequisites

• I have searched existing issues and confirmed this has not been requested.

Problem / motivation

some games when achievements are fetched come unlocked cause the accounts the achievements are fetched from already have some unlocked.

Proposed solution

after fetching achievements for a lua game, lock them.
if a game is updated or new achievements are later added, lock the new ones.

its not easy to implement that..

you can do this manually by using SAM to go to the game and lock them yourself after the game is initially added
