lib: add Peer Manager

Adds the Peer Manager.

List of changes compared to nrf5 SDK:

* Restructured and moved headers to dedicated folders

* Applied `clang-format-15` to each file

* Updated all licenses

* Replaced `ret_code_t` with `uint32_t`

* Connection state flags are not present in `ble_conn_state` so
  use the Kconfig `BLE_CONN_STATE_USER_FLAG_COUNT` instead.
  Convert the type `ble_conn_state_user_flag_id_t` to `int`.

* The configurable values defined in `peer_manager.packsc` have
  been converted to Kconfig options with a python script, and
  replaced in the code.

* Reformatted all Doxygen to fit NCS style

* Removed nrf5 SDK logging in favor of Zephyr logging

* DOS to unix line endings

* Fix Checkpatch

* Use Zephyr assert in `sdk_macros.h`

* All includes of headers that do not exist in Bare Metal have
  been removed.

* Changed `NRF_ERROR_RESOURCES` to `NRF_ERROR_DATA_SIZE`.
  This is in order to use `NRF_ERROR_RESOURCES` in stead of
  `NRF_ERROR_STORAGE_FULL`.

* Changed `NRF_ERROR_STORAGE_FULL` to `NRF_ERROR_RESOURCES`.

* Put central logic compilation behind Kconfig flag

* Add some extra build dependencies

* Update GATT Cache Manager by porting `nrf_mtx` logic

* Update `peer_id` and `pm_buffer` to use `atomic_t`
