Bugfix: Split large RemoteOutputService gRPC message (https://github.com/bazelbuild/bazel/pull/28758)

### Description
Directories with too many output files creates unlimited gRPC messages for the `RemoteOutputService`. Limit the messages to `maxOutboundMessageSize`.

### Motivation
Large directory outputs from actions in combination with Remote Output Service gives:
```
ERROR: /code/.../BUILD.bazel:3:16: Action large_directory_ failed: (Exit 34): RESOURCE_EXHAUSTED: grpc: received message larger than max (18681338 vs. 4194304)
Target //:large_directory failed to build
```
Example `rules.bzl`:
```
def _large_directory_impl(ctx):
    output_dir = ctx.actions.declare_directory(ctx.label.name + "_")
    args = ctx.actions.args()
    args.add_all([output_dir], expand_directories = False)

    ctx.actions.run_shell(
        outputs = [output_dir],
        command = """
cd $1
for i in $(seq 1 100); do
    mkdir $i
    for j in $(seq 1 1000); do
        echo $i-$j > $i/$j
    done
done
""",
        arguments = [args],
        execution_requirements = {"supports-path-mapping": "1"},
    )
    return DefaultInfo(files = depset([output_dir]))

large_directory = rule(
    implementation = _large_directory_impl,
)
```
Example `BUILD.bazel`:
```
load("//:rules.bzl", "large_directory")

large_directory(
    name = "large_directory",
)
```
