Anatol Belski 45b115aeb0 block: raw: Implement punch_hole and write_zeroes ...

Implement punch_hole() and write_zeroes() for raw file backends using
io_uring and fallocate.

punch_hole() uses FALLOC_FL_PUNCH_HOLE to deallocate storage.
write_zeroes() uses FALLOC_FL_ZERO_RANGE to write zeros efficiently.

Both use FALLOC_FL_KEEP_SIZE to maintain file size.
