1.9 Release

• renamed Virtual Apple to Apple Rosetta 2
• fixed oversight for AMD CPU detection
• fixed bug for VM::BOCHS_CPU
• fixed VM::ALL thanks to @D00Movenok
• fixed MSVC compiler warnings thanks to @NotRequiem
• disabled VM::CURSOR, VM::RDTSC, and VM::RDTSC_EXIT by default

NOTE: It's been exactly a year since I've started and continuously maintained this project since September 2023, and I'm taking a break for a while. Not sure when the next release will be, but I'll try to come back to this project after I've recharged my energy while I'm focusing on some side projects I've been working on occasionally :)
