[CI][C++] macOS arm64 verification tasks fail due to missing grpc++ headers

[raulcd]

Describe the bug, including details regarding any error messages, version, and platform.

Since yesterday the nightlies for macOS arm64:
verify-rc-source-cpp-macos-arm64
verify-rc-source-integration-macos-arm64

have failed with:

 -- Forcing gRPC_SOURCE to Protobuf_SOURCE (SYSTEM)
CMake Warning at cmake_modules/FindgRPCAlt.cmake:25 (find_package):
  By not providing "FindgRPC.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "gRPC", but
  CMake did not find one.

  Could not find a package configuration file provided by "gRPC" (requested
  version 1.17.0) with any of the following names:

    gRPCConfig.cmake
    grpc-config.cmake

  Add the installation prefix of "gRPC" to CMAKE_PREFIX_PATH or set
  "gRPC_DIR" to a directory containing one of the above files.  If "gRPC"
  provides a separate development package or SDK, be sure it has been
  installed.

@kou could this be a side effect of the brew uninstall grpc here #33711 ?

[kou]

I think so.
Our self-hosted arm64 runner isn't ephemeral. I think that we should install grpc formula explicitly in a job that needs grpc formula.

The following patch may work:
