cros: Move ash test files next to the classes under test

Historically //ash has been inconsistent in its placement of FooTestApi,
TestFooDelegate, MockFoo, etc.

Top-level ash OWNERS have decided that this sort of test code should
live in the same directory as Foo, not in //ash/test.

Move the files, collapse //ash/test/BUILD.gn into //ash/BUILD.gn and
add a note to //ash/README.md
