Create initial split of //components/signin into internals/externals

//components/signin/core/browser contains three different types of code:

1. Code that forms the guts of IdentityManager and will form the guts of
the Identity Service implementation (e.g., SigninManager).

2. Code that will be clients of IdentityManager (e.g., SigninTracker).

3. Code that will be used on both sides (e.g., AccountInfo).

Currently, all of these are naturally grouped in the same GN target,
since there was never any distinction between them. However, we need to
separate them in GN now to enable converting the code in 2 to use
IdentityManager. This split will also define the scope of the conversion
of the codebase to IdentityManager: everything that is in 1 will need to
have its clients converted to use IdentityManager.

This CL performs an initial split, via the following process:

- Moved signin_manager(_base).*, profile_oauth2_token_service.*, and
  account_tracker_service.* into a new "internals" target that the
  existing target now depends on.
- Kept moving in code (and adding dependencies as needed) until
  "gn check" no longer complained about the "internals" target including
  code that wasn't in any dependencies.

This CL also modifies //services/identity/public/cpp to depend only on
//components/signin/core/browser:internals; this change is is the
concrete benefit from doing the split, as it is what will allow us to
convert client code in //components/signin/core/browser.

Future CLs will refine the split, but this is a good initial checkpoint.

Remove unneeded include from test_signin_client.cc

This include causes complications when splitting
//components/signin/core/browser:test_support into "internals"
and "externals" targets: test_signin_client.h will go into the
"internals" target, which should not depend on
//components/signin/core/browser, which the included file is part of.

Happily, this include isn't used and can be removed :).

Create initial split of //components/signin test_support target

//components/signin/core/browser contains three different types of code:

1. Code that forms the guts of IdentityManager and will form the guts of
the Identity Service implementation (e.g., SigninManager).

2. Code that will be clients of IdentityManager (e.g., SigninTracker).

3. Code that will be used on both sides (e.g., AccountInfo).

Currently, the test support for all of these is naturally grouped in the
same GN target, since there was never any distinction between them.
However, we need to separate this test support in GN now, as the test
support for IdentityManager should depend only on 1 and 3 (and their
associated test support).

This CL performs an initial split, via the following process:

- Moved fake_signin_manager.*, fake_profile_oauth2_token_service.*, and
  fake_gaia_cookie_manager_service.* into a new "test_support_internals"
  target that the existing target now depends on.
- Kept moving in code (and adding dependencies as needed) until
  "gn check" no longer complained about the "test_support_internals"
  target including code that wasn't in any dependencies.

This CL also modifies //services/identity/public/cpp:test_support to
depend only on //components/signin/core/browser:internals_test_support;
this change is is the concrete benefit from doing the split.

Finally, this CL strips both the test_support_internals and the
test_support target down to the dependencies that they actually need;
this change necessitated added some missing direct dependencies to
other targets.

Create target in //components/signin for shared code

//components/signin/core/browser contains three different types of code:

1. Code that forms the guts of IdentityManager and will form the guts of
the Identity Service implementation (e.g., SigninManager).

2. Code that will be clients of IdentityManager (e.g., SigninTracker).

3. Code that will be used on both sides (e.g., AccountInfo).

1 and 2 have already been split via a preceding CL. This CL creates 3.
To start off with, 3 contains two pieces of code that were already in
their own standalone targets for similar motivations as the above:
account_info.* and signin_metrics.*. In the future more code will
likely move in.

This split is complete. There will be further work to do to analyze the split, determine what to do about bad inclusions/dependencies, and refine it, but we can track that elsewhere.

Change Identity Service impl to depend only on signin internals

Now that a distinct GN target exists just for the code backing
IdentityManager/Identity Service, change the Identity Service
implementation to depend only on that target. The change worked right
out of the box -- good validation of the initial split.

//components/signin: Move switches/prefs into shared target

We'll see where things go long-term, but for now, these seem more
intuitively like shared code than internal code.
