Fuchsia: Use SDK manifest for CC prebuilt and source packages.

Finishes the switch from using hand-rolled SDK target definitions to
using targets automatically generated from SDK metadata files. A
slightly oddball Vulkan copy rule remains intact.

* Remove the old targets from fuchsia_sdk/BUILD.gn
* Switch existing dependents of fuchsia_sdk:* targets to use
  fuchsia_sdk/sdk:* instead.
* Some "gn format" fixups.
