asio-grpc: fix test_package failures

[valgur]

Summary

Changes to recipe: asio-grpc/[*]

Motivation

Fixes two test_packages errors (when building as shared).

1. Adds VirtualRunEnv(self).generate(scope="build") to fix protoc execution:

protoc --cpp_out conan-center-index/recipes/asio-grpc/all/test_package/build/gcc-11-x86_64-17-release/generated  -I conan-center-index/recipes/asio-grpc/all/test_package --grpc_out conan-center-index/recipes/asio-grpc/all/test_package/build/gcc-11-x86_64-17-release/generated --plugin=protoc-gen-grpc=.conan2/p/b/grpc11cfe08c6d1ac/p/bin/grpc_cpp_plugin conan-center-index/recipes/asio-grpc/all/test_package/test.proto
.conan2/p/b/grpc11cfe08c6d1ac/p/bin/grpc_cpp_plugin: error while loading shared libraries: libgrpc_plugin_support.so.1.54: cannot open shared object file: No such file or directory
--grpc_out: protoc-gen-grpc: Plugin failed with status code 127.

2. Adds self.requires("protobuf/3.21.12") for asio_grpc_protobuf_generate() to fix linking:

These regressions are perhaps due to changes to the protobuf and/or grpc recipes a couple of months ago.

/cc @jcar87 since you were closely involved with the protobuf and grpc recipes.
