In order to regularly build the javase and reference docs images, I have
made the following changes:
1. Introduced bundle targets for the javase and reference docs images.
2. To run this in CI without adding more unnecessary build time to the
linux-x64 target (where the current docs are built), I created a new jib
profile "docs". This will run in a separate task and will build all 3
docs targets.
3. To enable the docs targets to run standalone without having to build
a full JDK, I had to tweak the "build-jdk" concept a bit, to allow it to
also function when not cross compiling for certain parts of the build.
Specifically the buildtools-modules can now be built by a "build-jdk"
instead of the exploded image.
4. For symmetry, I renamed variables and targets involving docs images
to always include one of "jdk", "javase" or "reference" in the name. See
below for targets.
The new top level targets are:
docs-{jdk.javase,reference}-image:
Aliases for the existing docs-{jdk,javase,reference} added for
consistency. The old docs-image is now an alias for docs-jdk-image.
all-docs-images:
Builds all 3 of the above docs images.
docs-{jdk,javase,reference}-bundles:
Builds the bundles for each kind of docs image. The existing
docs-bundles is now an alias for docs-jdk-bundles.
all-docs-bundles:
Builds all the docs bundles.
