[BH-1815] Optimalize loading music files in relaxation

Add relaxation list refresh after files added or deleted

[BH-1688] Create a standard for logs

* Adding document describing how to use logger
* Adjusting logs to follow a new guide
* Change order in log header:
  line number is now before function name

[CP-1962] Add Harmony color detection

* Added serial number based Harmony color
detection.
* Unified serial number handling for both
products.

[MOS-856] Another approach to MTP path in DeviceInfo

This time it's device-agnostic from purefs paths

[MOS-856] Add MTP path to DeviceInfo endpoint

Added MTP path for products to enable MC to use it instead
of hardcoded paths

[MOS-807] Fix MTP root path

Fixed MTP root paths for both Harmony and
Pure due to the MTP implementation
not supporting hierarchical directories.

[MOS-807] Update scripts

Added update scripts for both variants:
UDM update and further 'normal' updates.

Minor updates to the directories layout

[MOS-803] Further fixes for sync

Fixed paths for sync process
Added timeout for windows in recovery processes

[MOS-803] DeviceInfo endpoint update

* Added some changes to the DeviceInfo endpoint
* Updated relevant code accordingly
* Removed unneeded paths definitions
* Minor bug fixes

[MOS-783] Change boot.bin to os.bin

Change the confusing system binary name.

[MOS-783] Fixed tests and simulator for Harmony

Fixed tests and simulator for Harmony
after implementation of new filesystem
structure.

[MOS-783] Moved battery config file to '/user/data'

Moved battery config file from root
directory of user partition to
'data' directory to comply with
new directory layout design.

[MOS-783] Fixed Pure unit tests

Fixed (most of the) hardcoded
paths in Pure's unit tests.

[MOS-783] Working Pure simulator after partition changes

Fixed iosyscalls so that Pure simulator
works after directory structure changes.

[MOS-786] Added A/B booting support in OS

Added basic support for A/B booting

[MOS-783] First part of new dir structure implementation

    Works:
    - generating .img for Pure;
    - Pure boots after flashing new image and
    seems to be working fine;

    Not yet:
    - generating update package;
    - generating image for Harmony;
    - simulator;
    - path-related unit tests fail
    due to paths being hardcoded
    in test scenarios.

[CP-1427] Cleanup leftovers after old backup restore implementation

The synchronization mechanism has been freed from the constraints
of the old backup and restore implementation.

[MOS-694] Move DB initialization from OS to build scripts

* Switched to DB initialization at compile time
* Organized and cleaned up db files directories(not finished completely)
* Fixed DB related unit tests
* Minor improvements to CMake
* Small fixes for GCC12 build

[CP-1484] Add new mechanism for data synchronization between MOS and MC

This mechanism is similar to the current backup implementation,
but is stripped of irrelevant data that is not required by the
MC to perform data synchronization.

[CP-1560] New user directory structure

* New user directory implemented.
* Generate user directory structure at compile
time instead of at runtime(Pure/Harmony).
* Changed MTP root path to /storage
* FileIndexer: Minor refactor
* FileIndexer: Fixed handling incorrect/non-existing
scan directories.
* Updated Repository module to correctly handle
many assets paths.
* MultimediaDB: Minor unit tests refactor and fixed
some issues when using simulator.
* MultimediaDB: Added new queries and unit tests
* Harmony/Relaxation: Updated to correctly
use audio assets from more than one source.
* Harmony/Relaxation: Updated model and list items
provider.
* Harmony/Relaxation: Fixed stack overflow in audio service
