Revert "Migrate some internal-only ios and android entries to public DEPS."

This reverts commit 00dd1b27.

This commit introduced non-public dependencies to chromium/src.git.
These dependencies are protected behind the checkout_google_internal
flag. However, the pipeline which processes src.git for codesearch
does not understand or respect gclient conditionals. This caused
the pipeline to attempt to crawl these internal repos, and to
fire alerts when it consistently failed to do so.

This change is a temporary revert of the introduction of these
internal dependencies. When the codesearch deps-to-submodules
pipeline has been updated to respect gclient conditionals, we
can reland the change.

> This is an expanded version of the ios_internal change in
> https://crrev.com/c/880903, which should be more acceptable to the
