[bt][sm] Add Phase 1 class of pairing

Phase 1 is the first class to exist in an active pairing state machine.
As an initiator, it is responsible for building and sending the Pairing
Request. As a responder, it is responsible for parsing the peer's
Pairing Request and sending a Pairing Response. As initiator or
responder, it resolves the Pairing Request/Response into a higher-level
set of pairing features.

Bug: 46278
Test: Run with `fx run-test bluetooth-tests -t bt-host-unittests -- \
                --gtest_filter="SMP_Phase1*" `
      New Phase 1 tests have added:
      FeatureExchangeBothSupportSCFeaturesHaveSC,
      FeatureExchangeLocalSCRemoteNoSCFeaturesNoSc,
      FeatureExchangeResponderBothSupportSCFeaturesHaveSC,
      FeatureExchangeResponderLocalSCRemoteNoSCFeaturesNoSC,
      Phase1ResponderRejectsPairingRequest

      The rest have been translated from sm/bearer_unittest.cc:

      The list of tests from sm/bearer_unittest.cc not translated to
      phase_1_unittest.cc:
      PacketsWhileIdle (tested in IdlePhase), FeatureExchangeErrorSlave
      (tested by death tests), FeatureExchangeTimeout (now in Manager),
      Abort (now ActivePhase), FeatureExchangeResponderTimerRestarted
      (in Manager), StopTimer (in Manager), Confirm/Random value
      related tests (now in Phase 2), Identity/Identity Address related
      tests (now in Phase 3), OnSecurityRequest... (now in IdlePhase)
