C++ standard enforces copy elision in this case. and copy elision is
more performant than constructing the return value with a move
constructor, so no need to use `std:move()` here.
and GCC-14 rightfully points this out:
```
/home/kefu/dev/scylladb/lang/lua.cc: In member function ‘data_value {anonymous}::from_lua_visitor::operator()(const utf8_type_impl&)’:
/var/ssd/scylladb/lang/lua.cc:797:25: error: redundant move in return statement [-Werror=redundant-move]
797 | return std::move(s);

/home/kefu/dev/scylladb/lang/lua.cc:797:25: note: remove ‘std::move’ call

Similarly to previous patch, lua context needs db::config for creation.
It's better to get the configurables via lang::manager::config.
One thing to note -- lua config carries updateable_values on board, but
respective db::config options and _not_ LiveUpdate-able, so the lua
config could just use simple data types. This patch keeps updateable
values intact for brevity.

without `FMT_DEPRECATED_OSTREAM` macro, `UUID::to_sstring()` is
implemented using its `fmt::formatter`, which is not available
at the end of this header file where `UUID` is defined. at this moment,
we still use `FMT_DEPRECATED_OSTREAM` and {fmt} v9, so we can
still use `UUID::to_sstring()`, but in {fmt} v10, we cannot.
so, in this change, we change all callers of `UUID::to_sstring()`
to `fmt::to_string()`, so that we don't depend on
`FMT_DEPRECATED_OSTREAM` and {fmt} v9 anymore.

This change removes inet_addr_type_impl::to_sstring()
and replaces its usages with fmt::to_string().
The removed helper performed an uneeded copying via
std::ostringstream::str().

Instead of the lua_slice_state which is local to this file. We want to
reuse the Scylla type <-> Lua type conversion functions but for that
they have to use the more generic lua_State*. No functionality or
convenience is lost with the switch, the code didn't make use of the
other fields bundled in lua_slice_state.
After previous patch hints manager class gets unused dependency on
snitch. While removing it it turns out that several unrelated places
get needed headers indirectly via host_filter.hh -> snitsh_base.hh
inclusion.

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
