Update to support M1 architecture

[kikiya]

Currently the install fails when using on M1 architecture Macs but the current fix is pretty straight forward:

Based on issue protocolbuffers/protobuf#8557

We should be able to add these lines and might want to reference the above PR in comments.

case "arm64":
          return makeDownloadFile("osx-x86_64"); 

The change should be added in this block --

One more step is some details about building the docker image using docker buildx with amd64 as platform.

Adding that osx-x86_64 then goes on to fail with

[ 66%] Building C object CMakeFiles/cpu_features.dir/src/cpuinfo_arm.c.o
In file included from /Users/johan/Code/Lightbend/akka-serverless/akkaserverless-javascript-sdk/sdk/node_modules/cpu-features/deps/cpu_features/src/cpuinfo_arm.c:15:

in "cpu_features" google/cpu_features#150

So looks like moving forward with this is blocked by that

Looks like this may be fixed by the switch in what proto/grpc tooling we use in current main.

[johanandren]

Almost, it is not possible to build the kalix-tools because it depends on a native image of the codegen which is not available for Macos arm64.

[johanandren]

I got that to work locally by doing the following:

• install a graalvm that works on m1 ("22.1.0.r17-grl" with sdkman)
• point the nativeImageGraalHome in kalix-codegen-js-cli to the graal directory
• sbt kalix-codegen-js-cli/nativeImage
• copy the built binary somewhere
• set/export env KALIX_NPMJS_CODEGEN_BINARY to the complete path of that somewhere

Looks like CircleCI doesn't yet support M1, so we won't be able to automate this yet.

Can it just run the x64 codegen binary via rosetta for now? (don't have an M1 mac to try it out)

Looks like there are protoc versions with osx-aarch downloads now.

Will nativeImageVersion := "22.1.0" work to have an M1 compatible graalvm downloaded automatically?

[pvlugter]

Longer term, could make more sense to convert the codegen over to TypeScript, and not have the native image binaries.
