Change the target type of platform_wtf to source_set.

A CL (https://codereview.chromium.org/2741343017) failed to compile on
Windows Debug try bots because files in wtf/ lacked __declspec(dllimport)
even though they need to import symbols defined in platform_wtf.

Conceptually, platform_wtf and wtf are a single link unit, thus the target
type of "component" was inappropriate; it should have been "source_set"
instead.

This change is supposed to fix the compile error mentioned above.

Context: part 4 could not be landed because of Windows build
failure. I think this will fix the issue.

PTAL?
