Cannot run tests on windows RBE from linux host due to missing files

### Description of the bug:

When trying to test a `py_test` target on Windows RBE from a linux host, we get the following errors:

```
ERROR: : Testing failed: missing input file '@@bazel_tools//tools/test:tw.exe'
ERROR: : Testing failed: missing input file '@@bazel_tools//tools/test:xml.exe'
ERROR: : Testing failed: 2 input file(s) do not exist
```

Looks like these 2 binaries are prebuilt and only bundled with the Windows build of bazel:
https://github.com/bazelbuild/bazel/blob/818c4c8de8b5ff7cd41cc25f3b2f7f61dac82432/tools/test/BUILD#L51

Start with tools/test/BUILD, especially the entries for tw.exe and xml.exe, and reproduce a py_test target on a Linux host using Windows RBE. Trace how these prebuilt test binaries are packaged and made available to the remote test action; done means the Windows RBE test no longer reports either file as missing.
