Introduce Identity Service and its initial usage

This CL introduces the Identity Service and converts the implementation
of the chrome.identity.GetProfileUserInfo() extension function to use
the new service. Notable points:

- The Identity Service is embedded in //chrome rather than //content,
  as it needs access to per-Profile classes with //chrome-level
  factories.
- The initial API is simply enough to satisfy the needs of the initial
  consumer. We will build out this API by incrementally converting
  further consumers.
- In the long term, the //components/signin classes on which the
  Identity Service depends will be folded into the Identity Service
  implementation, and their consumers will be converted to consume the
  Identity Service.
- The Identity Service makes use of the existing AccountId Mojo struct.
  It extends that struct to be nullable, as the Identity Service needs
  to be able to convey to a requesting client that the user is not
  signed in. Note that a separate HasPrimaryAccount() => bool method
  would not suffice here: since the communication is asynchronous, the
  user could always have signed out by the time that the Identity
  Service receives the GetPrimaryAccountId() call.

BUG= 683120 , 683124
TEST=Install a Chrome extension with the identity and identity.email
permissions in its manifest. Go to chrome://extensions, enable developer mode,
and inspect the background page of the above app. At the JS console that that
brings up, execute:
chrome.identity.getProfileUserInfo((account) => {console.log(account)})
Verify that the printout corresponds to the information of the account
being used for sync.

[ARC] Add browser test of ArcAuthService

In preparation for changing ArcAuthService to consume signin information
via the Identity Service, this CL adds a browsertest of ArcAuthService.

The initial test tests the flow for a user (non-managed) account when
background auth is performed. This is the flow that is the most
significant consumer of the Identity Service in the ARC auth code.
Specifically, we test that if Chrome is seeded with information for a given
account via the signin code, then when AuthInstance connects to ArcAuthService
and requests account info, it receives account info corresponding to the
seeded information.

Currently, we skip the merge session part of the auth flow in this test.
The merge session is difficult to interact with in a testing context, and
even with this flow skipped, the interaction between the ARC auth code
and //components/signin is basically fully exercised by the test.

In the future, we will aim to add tests of the following cases
(some of which might be easy, and others quite difficult):
- Error cases for background auth
- Merge session
- Manual authentication
- Robot accounts
- Managed accounts

[Identity Service] Add user manual

This CL augments //services/identity/README.md to be an in-progress
user manual that shows how to convert from using existing signin-related
interfaces to using the Identity Service for the same purposes. This
user manual will be extended over time as we continue to build out the
API surface of the Identity Service.

Embed the Identity Service in //ios/chrome's chrome_browser service

This CL embeds the Identity Service in //ios/chrome's chrome_browser
service in preparation for upcoming work that will connect to the
Identity Service on iOS. The embedding follows that done for //chrome.

As this is the first service embedded in //ios/chrome, there is some
setup work with manifest overlays done in this CL as well.

Finally, this CL adds an EarlGrey test that tests that the connection to
the Identity Service is set up. This test can and should be extended to
test setup of other services as those are embedded in //ios/chrome.
