Reland "Reland "Reland "Split WebKit platform build file"""

blobs.mojom-blink.h internally depends on url.mojom-blink.h.
So, we should have //url/mojo:url_mojom_gurl_blink__generator
dependency in blob:generator target on which other test_support
source_set depends.

confirmed that generated ninja files, i.e.
../obj/third_party/WebKit/Source/platform/loader/test_support.ninja
has a dependency to obj/url/mojo/url_mojom_gurl_blink_generator.stamp

This is a reland of 1cf9f36e
Original change's description:

> test_support of platform/loader and platform/network should
> depends on //storage/public/interfaces:interfaces_blink__generator
