Remove abstract classes for memory dumper

Remove abstract classes for memory dumper

WebProcessMemoryDump and WebMemoryAllocatorDump are abstract interfaces
because they lived in public/platform. Now they live in platform so there
is no reason to have such abstractions. Unify them with their impl classes.
This CL also replaces WebString with String.

PTAL?

This would be the last CL for dumper related clean-up in blink.
