📄 Description

As of macOS 15.4 it seems Rosetta 2 has implemented support for the remaining instruction sets we need. Therefore this PR:

Removes any macOS-specific CPU patching code in favor of using the native Rosetta 2 instruction support.
Removes the BMI1 patches as those are now only useful for old Intel CPUs beyond our minimum, which are still not working anyway due to other issues and probably not going to perform very well with the emulator anyway.
Cleans up any now-unused CPU patch support code.
Bumps the minimum macOS version from 14.0 to 15.4 going forward.
- Minimum for Apple Silicon was already 15.0 and Intel Macs are currently not functioning due to GPU issues.

This leaves the following remaining CPU patches:

TLS patches for Windows and Linux
SSE4a patches for non-AMD CPUs
