Pass WebThreadScheduler to Platform::Initialize() instead of WebThread.

This CL changes the interface of Platform::Initialize() so each embedder just
needs to pass a WebThreadScheduler for the main thread. This simplifies the
Blink initialization and reduces the necessity of WebThread in content/ and
elsewhere.

Some dirty workaround is necessary to deal with the issue on blink_platform_
unittests. This test suite does not set up a global task environment; instead,
each test sets up one in its test fixture. This does not work well with how
SimpleMainThread works. See comments in the CL for details.
