Move the installation rules of boot images to soong

This CL adds moves the installation rules of boot images to soong. This
will eventually allow us to build devices by skipping `katiBuild` and
moving straight to `katiPackaging`

Details
1. Drop `no_full_install` from dex_bootjars singleton. This ensures that
   the files installed by this singleton module does not get skipped
when generating the soong installs file (out/soong/installs-*)
2. Replace PackageFile with InstallFile. This registers the installation
   rules for both make-built and soong-built images (e.g.
aosp_cf_system_x86_64)
3. Implement `AndroidMkEntries` for dex_bootjars singleton. OutputFile
   needs to be non-nil so that this module does not get elided when
generating out/soong/Android-*. `OutputFile` was abritrarily set to one
of the many files installed by this singleton.
