Fixed HSP sound quality issues:
- fixed HF caused by invalid output block size during interpolation of
the bluetooth input,
- increased block size to increase time send interval to 8ms
Fixed issue with error handling when writing to overflowed stream.

Increasd io stream buffers:
- 64kB for big files with short lifetime scope
- 16kB for big files with long lifetime scope
- 1kB - dont changes default forr the rest
Split module-utils into smaller components for better dependency
management. Fix many dependencies throughout the project.

Adapted both codec and HFP profile to be able to work together.
Now it's possible to stream 2-way audio via HFP profile, but it
has to be integrated properly with EGD-7405
Add voice transcoding during phone call with two basic transforms:
- sample rate downscaling by a factor of 2 with a decimator
- sample rate upscaling by a factor of 2 with an interpolator (no
low-pass filter)

This refactoring removes invalid interface dependencies of the original
AudioDevice implementation:
- move things characteristic to RT1051AudioCodec to audio::codec
- remove dead methods
- make start/stop optional and codec configuration independent
- add more convenient way to get supported formats

Replace faulty implementation which produced ambiguous results with one
which is suited for both phone calls and music playback requirements,
including A2DP and HSP Bluetooth profiles.

Add basic interpolator and decimator to change sample rates by a factor
of a prime number. Interpolator repeats samples forming a stair signal,
while decimator drops excessive samples.
Templates have been used to utilize fast integer operations contrary to
byte-by-byte operations for number of bit width vs channel count
combinations.

Add a mechanism to apply a data transform on the stream's input. An
example mono to stereo transform is provided.

Added volume control feedback during music playback over Bluetooth.
Changed volume buttons handler logic in service audio to use actions
instead of messages.
Refactored Audio settings API.
Moved phone modes logic from serivce audio to service clients level.
Removed redundant API.
Seprated API for vibration and sound enable/disable.
Fixed issues with vibrations logic.
Check if decoder's file format is supported by the sink audio device
before playing the sound. Add list of supported formats to each of audio
devices.

Fix microphone mute during the phone call.
Previously phone would unmute on:
- connecting/disconnecting a jack
- turning loudspeaker on/off
- switching to the bt device.
Forced each message to have declared type as parts of Bus logic
depends on it and previously we encountered undefined
behaviours. Added tests and messages validators.
Add basic playback capability using Bluetooth A2DP profile.
Only stereo/44100/16bit files are supported at the moment

Removed duplicated mode observer from application
that was introduced during the rebase in this commit
1860bf210f.
Fixed mute logic according to the design.
Fixed switching back to the meditation window.
Verify stack usage of:
- ServiceAudio
- application music player
- decoder worker
Change if possible to a realistic value keeping a 30% margin.
Stack usage reduction is limited due to an extensive stack usage of
every call to the filesystem, which uses around 2 kB of stack.
