[Proposal] build xcframeworks M1 compliant (ios-arm64_armv7 & ios-arm64_i386_x86_64-simulator)

Hi all,

I have a Mac M1 available and I would like to try to contribute by compiling the xcframeworks that have slices for iPhone and for Simulator. Personally I would like to try with JRE.

Currently as a workaround to make it work on iPhones, I add this line to Xcode in the `Header Search Paths` section:
`A_PATH/JRE.xcframework/Versions/A/Headers`
because importing the xcframework in the `Frameworks and Libraries` section is not enough.

BTW, thanks! You are doing an amazing job.
