these unused includes were identifier by clang-include-cleaner. after
auditing these source files, all of the reports have been confirmed.
please note, because quite a few source files relied on
`utils/to_string.hh` to pull in the specialization of
`fmt::formatter<std::optional<T>>`, after removing
`#include <fmt/std.h>` from `utils/to_string.hh`, we have to
include `fmt/std.h` directly.

We have enabled the command line options without changing a
single line of code, we only had to replace old include
with scylla_test_case.hh.
Next step is to add x-log-compaction-groups options, which will
determine the number of compaction groups to be used by all
instantiations of replica::table.

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
Todays alloc() accepts migrate-fn, size and alignment. All the callers
don't really need to provide anything special for the migrate-fn and
are just happy with default alignof() for alignment. The simplification
is in providing alloc() that only accepts size arg and does the rest
itself.

A plain array of elements that grows and shrinks by
constructing the new instance from an existing one and
moving the elements from it.
Behaves similarly to vector's external array, but has
0-bytes overhead. The array bounds (0-th and N-th
elemements) are determined by checking the flags on the
elements themselves. For this the type must support
getters and setters for the flags.
To remove an element from array there's also a nothrow
option that drops the requested element from array,
shifts the righter ones left and keeps the trailing
unused memory (so called "train") until reconstruction
or destruction.
Also comes with lower_bound() helper that helps keeping
the elements sotred and the from_element() one that
returns back reference to the array in which the element
sits.
