www/node: Update 14.14.0 -> 15.0.0
Update to the latest major release of Node.js, which includes many
significant changes. Users are encouraged to read the release notes
While here, refresh existing patches with `make makepatch`, removing
some powerpc* related patches that have been adopted/reworked upstream
Remove the dependency on dns/c-ares and use the bundled version
instead, since Node.js has adopted a change to c-ares that has not yet
been released. The dependency will be re-added once dns/c-ares has
been updated to a release that contains support for CAA DNS records.
An UPDATING entry has also been added to include a notice about this
major version upgrade, and steps users can take to continue using the
v14.x line, which is now LTS.
