core/cheats: Add and change a few functions

Browse Source 
Added a few interfaces for adding/deleting/replacing/saving cheats. The cheats list is guarded by a std::shared_mutex, and would only need a exclusive lock when it's being updated.

I marked the `Execute` function as `const` to avoid accidentally changing the internal state of the cheat on execution, so that execution can be considered a "read" operation which only needs a shared lock.

Whether a cheat is enabled or not is now saved by a special comment line `*citra_enabled`.
