Fix //content/test:test_support under component builds.
Previously, //content/test:test_support depended directly on *_sources
targets. In component builds, this caused the browser_tests and
content_browsertests binaries to include their own copies of content as
well as depend on libcontent.so. This caused browser_tests and
content_browsertests to crash on startup. This CL changes test_support
to depend on the targets that forward to //content in component builds
and introduces such targets for gpu and ppapi_plugin.
The test_support changes also exposed underspecified dependencies in
extensions/renderer/BUILD.gn and third_party/libjingle/BUILD.gn, and
incorrect generated file dependencies in content/browser/devtools; the
generated files depend on other non-generated files so have to be
directly included in //content/browser.
