[EGD-3469] Fix assets and image creation

Preparing and copying of assets to the image was unreliable.
Switched from cmake mechanism to rsync, making resulting
scheme universal and reducing output folder pollution.

[EGD-6156] Create crash dumps

Integrate the CrashCatcher library in order to store phone state after
a fault occurs. The dumps are stored in the CrashCatcher hex format and
can be debugged using the CrashDebug stub built for x86_64 via the
'debug_crash_dump.sh' script.

[EGD-5565] Fix update process on new lf filesystem

These changes are needed for update to work with new
LFS fileystem, also minor bugfixes are included.

[EGD-6013] Fix no copy syscall

Due to lack of some filesystem syscalls std::filesystem::copy
functions family doesn't work. This path add missing syscalls
in the FS layer.

[EGD-5757] Fix backup API

Fix backup endpoint to work with new paths and FS api
The flow is based on the design in confluence.

[EGD-5737] Fix filesystem unit tests

Remove old VFS and utils::filesystem calls
Update unittest lists

[EGD-5737] Fix ugly crash on boot

Fix ugly crash on boot fs

[EGD-5737] Merge master into experimental

Keep experimental up to date with changes from master

[EGD-5609] Fix lfs partition erase size bug

Storing LFS erase size in the boot byte is not possible
because Linux kernel is unable to detect the partitions
after change boot bytes to values other than 0x80 or 0x00

In this patch LFS_BLOCK_SIZE is moved to the second
MBR bootcode AREA

[EGD-4495] Check partitions during registering new disk image

Check partitions validity when registering disk.

[EGD-5515] Remove unused code lfxextension

Remove unused code for detecting block size from user blocks

[EGD-5072] Refactor legacy VFS functions

Functions were refactored and renamed for better readability.
Some of them were moved to different files. In stat_vfs function
the order of member initializations was corrected.

[EGD-5392] Add switch vfat to RO mode

VFAT partition should be mounted in RO mode by default
because writing to FAT filesystem is unsafe.
Writing is allowed only in the LFS filesystem.
If upgrade is needed FAT partition can be temporary
switched to RW mode using mount() syscall with REMOUNT flag
but it should be switched to RO mode again after upgrade.

[EGD-5146] Add read LFS block size from part

Add littlefs block size from partition bootable offset

[EGD-5350] Add increase lfs cluster size

Incrase LFS clustrer size and cache bitmap improve
