1. Move the work of `declare-1p-copy-files` to
`build/core/tasks/meta-lic.mk`.
2. Remove `$(LOCAL_PATH)/pathmap.mk` because the variables defined in
it are no longer used.
3. The variable `ONE_SHOT_MAKEFILE` is deprecated and can be removed
directly.
4. Move the work of `offline-sdk-docs` to
`build/core/tasks/offline-sdk-docs.mk` because Soong cannot specify
the output path to `$(OUT_DOCS)/`.
5. Move the work of `framework-doc-stubs` to `build/core/Makefile`
because Soong cannot specify the output path to
`framework-doc-stubs-metadata_intermediates`, and because
`SDK_METADATA_FILES` is a dependency of the SDK, it must be moved
before the SDK's dependencies are determined, and it cannot be moved
to `build/core/tasks`.
6. `ANDROID_BUILD_EMBEDDED` can be removed because the `.mk` files that
use this variable are currently not used.
