Move all the FooForTest methods on LocalBackend to instead be
methods on a new unexported forTest type which is then given out
to callers in other packages via an exported ForTest method
(panicking in non-test contexts) that returns that unexported type.
This is unusual style (exported returning unexported) but declutters
godoc and makes call sites both more explicit and easier to read
without the "ForTest" suffix polluting the symbols. Now FooForTest()
changes into ForTest().Foo().
This was motivated by a pending change moving a bunch of code out of
LocalBackend into other packages that required adding more ForTest
methods to LocalBackend to keep the tests (now in other packages)
working. Instead, do this refactor now so the future change is prettier.

To avoid breaking downstream code, add deprecated aliases for all the
old names.

The `CreateStateForTest` helper reduces boilerplate in cases where the test
only cares about the trusted keys and not the disablement values (and makes
it more obvious where the disablement values are meaningful).
The `setupChonkStorage` helper reduces the boilerplate when creating on-disk
TKA storage in tests.
The `fakeLocalBackend` helper reduces the boilerplate when setting up a
`LocalBackend` instance in the IPN tests.
