Changes to Bazel's java_tools to enable Error Prone auto-patching

Summary:
This diff contains the changes in bazelbuild#21640, ported to the uber/java/7.0.2.001 branch.  We also commit a modified version of the Error Prone check_api jar.  The modifications in that jar are those changes in google/error-prone#4318 applied to Error Prone 2.22.0 (the version used in our branch).  Probably, rather than committing the modified jar, we could upload the modified jar to artifactory and change the version we depend on here.

I have tested that these changes work locally on a devpod.  `IN_PLACE` patching will most likely not work under stronger sandboxes, as it relies on modifying the source files in the sandbox (which, by default on a devpod, are just symlinks to the original source files).

Also, there seem to be some weird interactions with the Bazel cache, such that when I tried to run the same autopatch twice (after undoing the initial changes), I had to blow away my local `~/.bazelcache` directory to make it work.

Test Plan:
Tested locally by copying over the built java_tools jars and running:

```
EP_PATCH_CHECK=MissingOverride EP_PATCH_CHECK_PATH_ONLY=a/b/c tools/bazel build //a/b/c:src
```

It would be good to write an integration test for this at some point, since it hasn't been upstreamed.
