Due to fd62fba985
scoped enums are not automatically converted to integers anymore,
this is the intended behavior, according to the fmtlib devs.
A bit nicer solution would be to use `std::to_underlying`
instead of a direct `static_cast`, but it's not available until
C++23 and some compilers are still missing the support for it.

The sstables::sstable class has two methods for writing sstables:
1) sstable_writer get_writer(...);
2) future<> write_components(flat_mutation_reader, ...);
(1) directly exposes the writer type, so we have to update all users of
it (there is not that many) in this same patch. We defer updating
users of (2) to a follow-up commits.
Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.
Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.
The changes we applied mechanically with a script, except to
licenses/README.md.
Closes#9937
metric currently_open_for_writing, used to inform # of sstables opened for writing,
holds the same value as total_open_for_writing. that means we aren't actually
decreasing the counter, so it is bogus.
Moved to sstable_writer, because sstable is used by writer to open files,
which are then extracted from sstable object, and later the same object is
reused for read-only mode.
Fixes#9455.

This class is used in only few places and does not have to be included
everywhere sstable class is needed.

This function is only called internally so it does not have to be
exposed and can be inlined instead.

Previous patch made MC the lowest sstables format in use so
the removed check is always true now and we can remove the else
part.

Add a mutation_fragment_stream_validating_filter to
sstables::writer_impl and use it in sstable_writer to validate the
fragment stream passed down to the writer implementation. This ensures
that all fragment streams written to disk are validated, and we don't
have to worry about validating each source separately.
The current validator from sstable::write_components() is removed. This
covers only part of the write paths. Ad-hoc validations in the reader
implementations are removed as well as they are now redundant.
