Add missing no jdk distributions (#4722)

* add missing no-jdk gradle targets for distributions

by convention all supported platforms should also have a gradle target
to produce a no-jdk build and that target should be called
`no-jdk-[platform]`.

this is a first step in the path to publishing the no-jdk distributions
as part of the release, as there are use-cases where a specific JDK
should be used instead of the packaged one and it's cleaner to use a
small distribution which doesn't bring along an unneeded JDK (the JDK
greatly increases the resulting distribution since).

note that i failed to rename the `linux-s390x` target, it seems that
there's too much generic build code out there which tries to stitch
together that name and then fails if it doesn't find it.

this is part of opensearch-build#99.

* add basic README for `:distribution`

this is primarily to document the JDK & No JDK setup (to codify it for
the future), however the README can be extended in the future to
document more information which is currently hidden away only somewhere
in the code.

+# Distributions
+This subproject contains the necessary tooling to build the various distributions.
+Note that some of this can only be run on the specific architecture and does not support cross-compile.
+
+The following distributions are being built:
+* Archives (`*.zip`, `*.tar`): these form the basis for all other OpenSearch distributions
+* Packages (`*.deb`, `*.rpm`): specific package formats for some Linux distributions
+* Docker images
+* Backwards compatibility tests: used internally for version compatibility testing, not for public consumption
+
+## With or Without JDK?
+For each supported platform there should be both a target bundled with a JDK and a target without a bundled JDK.
