This allows us to remove dependencies on SigninManager/ProfileOAuth2TokenService from these tests.

Convert MediaRouterContextualMenu unittest to IdentityTestEnvironment

This change is possible now that there is infrastructure for glueing
an IdentityTestEnvironment to a Profile.

Port GaiaInfoUpdateService unittest to use IdentityTestEnvironment

This is possible now that we have infrastructure that glues an
IdentityTestEnvironment instance to a Profile, and it enables removing
the test's knowledge of SigninManager.

Port EasyUnlockService unittest to IdentityTestEnvironment

This is possible now that there is //chrome-level infrastructure for
glueing an IdentityTestEnvironment instance to a Profile.

Note that this particular test is somewhat unusual in that it builds
multiple Profiles but does not require IdentityTestEnvironment to
interact with those Profiles beyond doing initial configuration. For
simplicity, we use local variables for the IdentityTestEnvironment
associated with each Profile; otherwise, we would need to introduce
distinct instance variables for the two.

This CL also modifies the relevant
IdentityTestEnvironmentProfileAdaptor APIs to return the
TestingProfiles that they create as TestingProfiles; this avoids a
cast that this test would otherwise require and clarifies the APIs.
