Add credstore system daemon.

The credstore system daemon is sitting below the Identity Credential
Framework APIs and on top of the Identity Credential HALs. Its main
job is to store credential data and provide a way for applications to
communicate with the secure hardware abstracted by the HAL.

This daemon runs as an unprivileged user, credstore.

The auth-tokens needed by credstore are supplied by keystore and this
CL includes the requisite changes to keystore for this to work.

Bug: 111446262
Test: CTS tests for Framework APIs
