## Description
This PR implements cheat support (patcher + engine) with a simple API to
provide Action Replay/Game Shark compatible cheats (with exception of
cheats that utilize GS button).
API consist of a single pointer to an array of the cheats ended with a
double zero entry,
For example, if you want to pass these cheats to the patcher:
```
D01F9B91 0020 // Majora's Mask (USA) Inventory Editor
803FDA3F 0002
```
Put cheats in a `uint32_t` array as such (notice last two entries are
zeros):
```
uint32_t cheats[] = {
0xD01F9B91,
0x0020,
0x803FDA3F,
0x0002,
0,
0,
};
```
And pass this array as a boot parameter: `menu->boot_params->cheat_list
= cheats;`
