The -libraryjars argument to r8 was missing transitive dependencies, and
so complained when there were classes used in the program JAR which were
not provided via libraries. This CL propagates transitive dependencies
to the r8 command to reduce the warnings that are generated for missing classes.

Upgrading dagger uncovers an issue where java-only modules with
kotlin-containing dependencies may see org.jetbrains.annotations.NotNull
annotations. Include the kotlin-annotations in the output jar the
same way kotlin-stdlib is included.

The kapt rule uses kotlincFlags but was not using kotlincDeps,
causing the rule to get the -Xplugin argument on the compose
compiler plugin jar, but not have a dependency on it.

When compling kotlin code with annotation processors we are generating
java stubs for the kotlin sources using kapt, and parsing them in
turbine when running the annotation processors. Passing --output
to turbine will also compile the stubs into a header jar that can
be used as a dependency to javac, allowing the javac and kotlinc
rules to run in parallel. The turbine-apt header jar can't be used
as the header jar for downstream modules as it doesn't contain the
kotlin metadata needed by kotlinc rules, so the kotlinc gen-jvm-abi
plugin output is still used for the module's final header jar.

Kotlin's jvm-abi-gen plugin can generate header jars similar to the
turbine output for java sources, which can be used to avoid recompiling
downstream modules when the ABI hasn't changed. Unlike turbine, the
plugin runs as part of the main kotlinc invocation, so it doesn't allow
the downstream modules to start compiling any sooner.
A future possible optimization is to use turbine to compile the kapt
stubs, at least for the kotlin+annotation processor modules that already
generate them, which would allow compiling downstream modules before
invoking kotlinc or javac, as well as invoking kotlinc and javac in
parallel with each other.

Follow Bazel by using turbine instead of kapt to run annotation
processors. This still requires using kapt to generate java stubs
of kotlin soruces, then uses turbine to run annotation processors
on the java stubs and any java sources to generate sources and
resources, and passes the annotation processor generated sources
to kotlinc and javac.

Currently, errorprone is only run if the RUN_ERROR_PRONE
enviornment variable is true. Add a flag that individual
modules can use to always enable errorprone.
In a followup cl, I plan to add another flag that will
force all errorprone checks to be errors, so that modules
can be confident that they're not ignoring any errorprone
checks.

Previous extra checks for ErrorProne were added using the plugins
proeprty to get them into the -processorpath argument. This works
fine for java-only modules, but fails for mixed java+kotlin modules
because the processorpath is given to kapt and not javac.
Add a dedicated errorprone.extra_check_modules property (mirroring
the lint.extra_check_modules property), and add that to a separate
processorpath that is used only for errorprone rules and not cleared
when kotlin is used.

kapt claims to support a comma separated list of annotation
processors, but it errors if multiple annotation processors
are given. Surrounding the the list with {} does not error,
but it also doesn't even warn if the second element in the
list is garbage, so it may not be running the second
processor. Repeat the processor argument for each
annotation processor class instead.

Now that there are no uses left of annotation_processors remove
the property.
If there are no annotation processor classes for javac for a module,
due to an empty "plugins" property or using kapt for annotation
processors, pass -proc:none to javac to ensure it does not try
to run any annotation processors found in the classpath.

Follow bazel's modules for annotation processors by introducing
a java_plugin module type that can contain extra metadata about
the annotation processor, the processor class and a flag to
specify if the annotation processor is compatible with the
turbine optimization. Deprecate the annotation_processors
property, which took a list of java_library_host modules, in
favor of the plugins property, which takes a list of java_plugin
modules. The annotation_processors property will be removed
once all uses have been replaced with plugins.
