Move mocks and unittest JS files to sit alongside production code.

Move mocks and unittest JS files to sit alongside production code.

Chromium normally places unit-test implementations alongside the class
implementations, so that it's easy to see what has tests and what
doesn't.

Similarly placing mocks next to the corresponding interfaces or classes
makes it easier to spot and re-use them.

PTAL

This CL moves the unittest.js files alongside the production code, to match the
way we lay things out in the C++ codebase, and renames the targets from unittest
to unittests for similar reasons.

Pawel, plz rubber-stamp the BUILD.gn change (which is just to a commented-out
line right now...)
