Reland "Integrate LegacyPairingState with ..." PairingStateManager"

This is a reland of commit 31a9d97a99e1571ad674961a0647b3de85d9265e

Relanding this with no changes. Originally reverted because there was no
configuration to disable/enable legacy pairing (added in fxr/1102453).

Original change's description:
> [bt][gap] Integrate LegacyPairingState with PairingStateManager
>
> This CL wires up the legacy pairing process code to the rest of the
> system via the PairingStateManager.
>
> Depending on the pairing events we encounter before/after the ACL
> connection is complete, or depending on the result of interrogation with
> the peer, we will tell the PSM whether to use SSP or legacy pairing.
>
> Bug: b/42173830
> Test: fx test //src/connectivity/bluetooth
> Manual Test:
> - Paired and streamed audio to/from Nelson DUT with iOS and veho devices
>   supporting SSP to ensure SSP still functions
> - Paired and streamed audio to/from Nelson DUT with iOS and veho
>   devices. Cherry-picked fxr/1078858 to simulate legacy pairing
