Use exclusiveContent gradle feature for jdk and distro downloads (#53358)

The jdk and distribution download plugins create fake ivy repositories,
and use group based repository filtering to ensure no other artifacts
try to resolve against the fake repos. Currently this works by adding a
blanket exclude to all repositories for the given group name. This
commit changes to using the new exclusiveContent feature in
Gradle to do the exclusion.
