Synchronize the upstream/downstream batch processor code (#251)

As I prepare to submit the concurrent batch processor code to the
upstream repository, I have developed the following proof-of-concept:


https://github.com/open-telemetry/opentelemetry-collector/pull/11248/files

I simplified, commented, linted, and tidied the code in that repository,
aiming to achieve the smallest diff possible w/ only the essential
features of this repository contributed back. This incorporates upstream
changes in metadata.yaml, metrics code generation, and related lint
improvements. Then, I copied the changed files back here.

No functional changes. I have eliminated the in-flight bytes metric and
the panic recovery feature, both nice-to-have but complicates the diff
and appear unnecessary.

Includes the upstream README.md, metadata.yaml, and generated code.
