Add the TamperMachine module for runtime mods and cheats (#1928)
* Add initial implementation of the Tamper Machine * Implement Atmosphere opcodes 0, 4 and 9 * Add missing TamperCompilationException class * Implement Atmosphere conditional and loop opcodes 1, 2 and 3 * Inplement input conditional opcode 8 * Add register store opcode A * Implement extended pause/resume opcodes FF0 and FF1 * Implement extended log opcode FFF * Implement extended register conditional opcode C0 * Refactor TamperProgram to an interface * Moved Atmosphere classes to a separate subdirectory * Fix OpProcCtrl class not setting process * Implement extended register save/restore opcodes C1, C2 and C3 * Refactor code emitters to separate classes * Supress memory access errors from the Tamper Machine * Add debug information to tamper register and memory writes * Add block stack check to Atmosphere Cheat compiler * Add handheld input support to Tamper Machine * Fix code styling * Fix build id and cheat case mismatch * Fix invalid immediate size selection * Print build ids of the title * Prevent Tamper Machine from change code regions * Remove Atmosphere namespace * Remove empty cheats from the list * Prevent code modification without disabling the tampering * Fix missing addressing mode in LoadRegisterWithMemory * Fix wrong addressing in RegisterConditional * Add name to the tamper machine thread * Fix code styling
