[Andrew John Hughes]

> Initial attempt to backport https://github.com/openjdk/jdk11u-dev/commit/1faefed218051c324bdb5c7c10369050d6c9dd44
> 
> Changes so far:
> * `make/autoconf/version-numbers` -> `common/autoconf/version-numbers`
> * Fix version variables (`JDK_MAJOR_VERSION`, `JDK_MINOR_VERSION` and `JDK_MICRO_VERSION` in 8u)
> * Remove boot JDK for Linux (provided by build environment Ubuntu 20.04 in openjdk-8-jdk)
> * Replace `--with-version-opt` with `--with-user-release-suffix`
> * Drop `--enable-jtreg-failure-handler` (unsupported)
> * Move make targets to make invocation (`--with-default-make-target` not supported)
> * Drop `--with-msvc-toolset-version`
> * Disable tests as we don't currently have the bundles required to support them
