Subject: [PATCH] [bazel] Add default shell env to gen_well_known_protos_java

We may need the shell environment (potentially augmented with
`--action_env`) to invoke protoc on Windows. If protoc was built with
mingw, it probably needs .dll files in non-default locations that must be
in PATH. Previously with `--compiler=mingw-gcc`,
`bazel build //:gen_well_known_protos_java` would fail on Windows. This
CL fixes the issue.

Also we have `default_shell_env` set to True for `ProtoCompile`, this makes
the behavior consistent.

See #2933, and
https://github.com/bazelbuild/rules_go/blob/585a27ad0ab5bdd185aa3bd5b0877a778d4777ad/proto/compiler.bzl#L130
