... and replace it with boolean enable_tablets option. All the places
in the code are patched to check the latter option instead of the former
feature.
The option is OFF by default, but the default scylla.yaml file sets this
to true, so that newly installed clusters turn tablets ON.

Closesscylladb/scylladb#19012
We make the `consistent-topology-changes` experimental feature
unused and assumed to be true in 6.0. We remove code branches that
executed if `consistent-topology-changes` was disabled.
before this change, we rely on the default-generated fmt::formatter
created from operator<<, but fmt v10 dropped the default-generated
formatter.
in this change, we include `fmt/ranges.h` and/or `fmt/std.h`
for formatting the container types, like vector, map
optional and variant using {fmt} instead of the homebrew
formatter based on operator<<.
with this change, the changes adding fmt::formatter and
the changes using ostream formatter explicitly, we are
allowed to drop `FMT_DEPRECATED_OSTREAM` macro.

Will be used by topology loading code to determine which hosts are
needed in topology, even if they're in the left state. We want to load
only left nodes if they are referenced by any tablet, which may happen
temporarily until the replacement replica is rebuilt.
get0() dates back from the days where Seastar futures carried tuples, and
get0() was a way to get the first (and usually only) element. Now
it's a distraction, and Seastar is likely to deprecate and remove it.
Replace with seastar::future::get(), which does the same thing.
when comparing signed and unsigned numbers, the compiler promotes
the signed number to coomon type -- in this case, the unsigned type,
so they can be compared. but sometimes, it matters. and after the
promotion, the comparison yields the wrong result. this can be
manifested using a short sample like:
```
int main(int argc, char **argv) {
int x = -1;
unsigned y = 2;
fmt::print("{}\n", x < y);
return 0;
}
```
this error can be identified by `-Werror=sign-compare`, but before
enabling this compiling option. let's use `std::cmp_*()` to compare
them.

The methods that take storage_proxy as argument can now accept a
replica::database instead. So update their signatures and update all
callers. With that, system_keyspace.* no longer depends on storage_proxy
directly.
