Fixes#26744
If a segment to replay is broken such that the main header is not zero,
but still broken, we throw header_checksum_error. This was not handled in
replayer, which grouped this into the "user error/fundamental problem"
category. However, assuming we allow for "real" disk corruption, this should
really be treated same as data corruption, i.e. reported data loss, not
failure to start up.
The `test_one_big_mutation_corrupted_on_startup` test accidentally sometimes
provoked this issue, by doing random file wrecking, which on rare occasions
provoked this, and thus failed test due to scylla not starting up, instead
of loosing data as expected.
Changed test to consistently cause this exact error instead.
- fix typos
- improve comments
- remove false and misleading comments
- remove `disableautocompaction` as it did nothing for the test
and the comment with it was false
The test is flaky since it tries to corrupt the commitlog
in a non-deterministic way that sometimes allows
the tested mutation to escape and be replayed anyhow.

test_pinned_cl_segment_doesnt_resurrect_data was not moved in #24946 from
scylla-dtest to this repo, because it's marked as xfail (#14879), but
actually the issue is fixed and there is no reason to keep the test in
scylla-dtest.
Also remove unused imports.
Closesscylladb/scylladb#25592
Tests test_total_space_limit_of_commitlog_with_large_limit and
test_total_space_limit_of_commitlog_with_medium_limit use too much
disk space and have too big execution time. Keep them in
scylla-dtest for now.
As a part of the porting process, remove unused imports and
markers, remove non-next_gating tests and tests marked with
`skip`, 'skip_if', and `xfail` markers.
test.py uses `commitlog` directory instead of dtest's
`commitlogs`.
Remove test_stop_failure_policy test because the way how it
provoke commitlog failure (change file permission) doesn't
work on CI.
Enable the test in suite.yaml (run in dev mode only)
