Enhancement: Refactoring Windows ARM64 - CPU Detection Logic

Current source code supports some pre-defined chips by hardcoded definitions:

https://github.com/pytorch/cpuinfo/blob/main/src/arm/windows/init.c

Currently information is stored in:

woa_chip_info woa_chips[woa_chip_name_last]

---

It would be better to add capability to detect new chips without breaking existing implementation.

Otherwise, this will generate "Unknown CPU" warning/error message for the all undefined ARM64 chips.

---

Example error/warning messages:

Error in cpuinfo: Unknown chip model name 'Snapdragon(R) CPU'.

The MIDR is stored in HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0\CP 4000 where \0\ is the cpu ID.

Have suggested we use that instead
