Install boot.art extra files individually

Install boot.art extra files individually

The rule that builds boot.art also produces boot.oat, boot-*.art, and
boot-*.oat as a side effect, and the install rule for boot.art was
installing them using *.art and *.oat.  This meant that PDK builds had
no rule to install the extra files, so it used the ones from the
platform.zip file instead of the locally built ones.

Generate a list of the files that should be produced by the boot.art
build, and manually create install rules for them that depend on the
built boot.art and are depended on by the installed boot.art.
