Request for Windows ARM64 Support in RocksDB-Sharp

[paululvinius]

I recently transitioned to a Windows ARM64 environment, a move that many others are making with the latest generation of laptops. With the growing adoption of Windows on ARM, it's clear that this platform is here to stay.

Given the increasing popularity of ARM64 for Windows, adding support for this architecture would be a significant and valuable enhancement for the rocksdb-sharp library.
