[EGD-4593] Dump logs to file on timeout

- Dump logs to file every 10 sec.
- max file size is 50 MB
  (after reaching it, no more logs will be logged),
- Add `LockGuard` with locking mechanism
  supporting IRQ and use it in `Logger`.
- Fix minor style issues in `Logger`.
- Add `mount_user_lfs_partition.py` script for mounting LFS on Linux FS
  in order to get `MuditaOS.log` file from `user` partition
