[cheats] add runtime cheats toggles with master code support (#4334)

add per-cheat runtime toggles (thread-safe).
add master code handling (master code cannot be disabled, as noted in Atmosphere's implementation).
add configurable global / per-game initial states for cheat entries.
remove fixed opcode limits and do some fixes to text parsing / file loading.
do not run debug log while cheat logging is not enabled, to reduce performance impacts.
update the `Using Cheats` document to reflect the changes.
