libobs: Add Windows X64 Emulation on ARM64 and move Rosetta Detection

[tommyvct]

Description

Adds a check that detects if OBS is running on Windows ARM64 emulation and logs the result.

Motivation and Context

#5644
I messed up #5738, this is the new PR.

How Has This Been Tested?

Running X64 OBS Studio gives the following log:
