Support M1 Mac Architecture for grpc-web

[kunal-rp]

Description

Mono-repo built on intel mac is failing for M1 architecture. The build target is a js grpc web library.

Support for darwin_arm64 will need to be added here :

tool = select({
        "@bazel_tools//src/conditions:darwin_x86_64": "@grpc_web_plugin_darwin//file",
        "@bazel_tools//src/conditions:linux_x86_64": "@grpc_web_plugin_linux//file",
        "@bazel_tools//src/conditions:windows": "@grpc_web_plugin_windows//file",
    }),

There is no official darwin-arm64 support for grpc-web plugin yet, but mirror link could be created following steps in this thread ? grpc/grpc-web#1159

Until they have an official ARM M1 build for the plugin, there's not a lot I can reasonably do to support it. Building the plugin myself is beyond the scope of this project and I don't have the necessary hardware anyway.

[kunal-rp]

It seems like there are github actions for grpc-web repo to build arm artifacts

would this be sufficient ?

Those builds look like they aren't yet attached to a published release. Once v1.4.0 or v1.3.2 is released hopefully they should have the right plugin executables to use here.
