Only depend on child sources from app in both target

Added here: This makes
chrome.dll depend on all of WebKit at build time.

This changes restores

c:\src\cr\src>gn path //out/Release //chrome:main_dll //third_party/WebKit/public:blink
No non-data paths found between these two targets.

Before this change, public_app_shared_sources was included into multi-dll browser, causing all the child deps to be linked in there.

( is about why assert_no_deps didn't catch this.)
