Historically, we've always passed '-I .' as the first argument to
protoc, essentially treating all proto file package names as their full
path in the android source tree. This would make sense in a monorepo
world, but it makes less sense when we're pulling in external projects
with established package names.
So keep the same default (for now), but allow individual builds to opt
into using local paths as the default names with
'canonical_path_from_root: false'. A cleanup effort and/or large scale
change in the future could change the default to false.
As part of this, run protoc once per input proto file, since the flags
may need to change per-file. We'll also need this in order to specify
--dependency_out in the future.

javastream proto is rarely used and tricky to support directly
in java because it depends on an extra host tool. It can be
supported with a genrule, so just remove the partial built-in
support.

Compute the common proto flags and pass them to the protoc invocation
when generating java files.

Now that android.ModuleContext does not include blueprint.ModuleContext
we can rename android.ModuleContext.ModuleBuild to
android.ModuleContext.Build without colliding with
blueprint.ModuleContext.Build. Leave ModuleBuild as a wrapper around
Build for now to avoid having to update all the users outside
build/soong simultaneously.

srcFileLists was an ill-fated attempt to deal with generators that
produce a set of java sources that is not known ahead of time.
For example, the list of files produced by protoc depends on the
package statement in the .proto file. srcFileLists put the list
of generated files into a file, which was then passed to javac
using the @file syntax. This worked, but it was too easy to cause
missing dependencies, and will not work well in a future distributed
build environment.
Switch to putting generated sources into a jar, and then pass them
jar to javac using -sourcepath.
