Add prebuilt support for macOS Intel (x86_64)

[jgsaez9]

Hi,

I noticed there’s already ARM64 support for macOS builds, but there’s no packaged release for Intel-based Macs (x86_64). There are still many users on Intel hardware (MacBook Pro, iMac, Mac Mini, etc.) who would benefit from having an official prebuilt binary.

Request:
Add a build target for macOS Intel 64-bit (x86_64-apple-darwin)

Provide downloadable binaries/releases for this architecture, similar to the ARM64 macOS build

This would greatly help the community, since compiling Chromium-based projects from source on macOS Intel can be extremely time-consuming and error-prone.

Thanks for considering this addition!
