Modularize failureaccess.

Modularize failureaccess.

This is the next piece of #7094, which is progress toward modularization.

I've modified this CL somewhat from the original version so that I can deploy a new version of failureaccess without needing to make any updates to guava-parent first. failureaccess does still use guava-parent (and I've bumped it to use the newest released version) for its configuration for Sonatype, Javadoc, etc. But I've inlined all the configuration that I need for the modularization.

I did note a few differences from the original version:

• This version includes LICENSE under META-INF, both in the main jar and in the sources jars.
• This version uses a different configuration for Javadoc, I assume because my recent changes there didn't make it into 33.4.0.

I also notice that neither version contains module-info.java in its source jar. We could presumably fix that in the future if anyone is interested.

(And while this isn't strictly related, I do notice that we could consider also releasing a modularized version of listenablefuture someday.)

I have tested with:

$ JAVA_HOME=$HOME/.m2/jdks/jdk-17.0.13+11 ./mvnw clean install -Psonatype-oss-release -Dmaven.test.redirectTestOutputToFile=true -Dsurefire.printSummary=false -Drelease -f futures/failureaccess

(Some of those flags aren't necessary, but I found it easiest to copy what our release script does for "normal" releases.)

I would use deploy instead of install for the real thing.
