Remove unused dependencies from sdk goals

The SDK no longer includes system images, so no longer needs to depend
on targets that are only relevant for the system images.

Remove all the explicit dependencies that end up depending on
"everything" but are not included in the sdk zip.

Two positive side-effects:
- fewer unused things get built (now ~32k targets, down from ~108k)
- apexes no longer get built, eliminating the risk of mismatch between
  module sdk prebuilts and source-built AOSP apexes.

There are some potential risks with this CL:
- because we no longer forcefully rebuild everything, if there are bugs
  in dependencies of exising files in the SDK, incremental builds may
  not rebuild them.
- some files that get built into the SDK may be being built as a
  side-effect of other files included in the SDK, so removing one file
  may cause another to not get built. The solution to that is to add
  the file not getting built to ALL_SDK_FILES.

Bug: 205008975
Test: m sdk sdk_repo dist && diff sdk.zip before/after (identical)
