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.

std::rel_ops was deprecated in C++20, as C++20 provides a better
solution for defining comparison operators. and all the use cases
previously to be addressed by `using namespace std::rel_ops` have
been addressed either by `operator<=>` or the default-generated
`operator!=`.
so, in this change, to avoid using deprecated facilities, let's
drop all these `using namespace std::rel_ops`.

this the standard library offers
`std::lexicographical_compare_threeway()`, and we never uses the
last two addition parameters which are not provided by
`std::lexicographical_compare_threeway()`. there is no need to have
the homebrew version of trichotomic compare function.
in this change,
* all occurrences of `lexicographical_tri_compare()` are replaced
with `std::lexicographical_compare_threeway()`.
* ``lexicographical_tri_compare()` is dropped.

UUID_test uses lexicograhical_compare from the types module. This
is a layering violation, since UUIDs are at a much lower level than
the database type system. In practical terms, this cause link failures
with gcc due to some thread-local-storage variables defined in types.hh
but not provided by any object, since we don't link with types.o in this
test.
Fix by extracting the relevant functions into a new header.
* throw marshal_exception if not the whole string is parsed, we
should error out if the parsed string contains gabage at the end.
before this change, we silent accept uuid like
"ce84997b-6ea2-4468-9f02-8a65abf4wxyz", and parses it as
"ce84997b-6ea2-4468-9f02-8a65abf4". this is not correct.
* throw marshal_exception if stoull() throws,
`stoull()` throws if it fails to parse a string to an unsigned long
long, we should translate the exception to `marshal_exception`, so
we can handle these exception in a consistent manner.
test is updated accordingly.

they are part of the CQL type system, and are "closer" to types.
let's move them into "types" directory.
the building systems are updated accordingly.
the source files referencing `types.hh` were updated using following
command:
```
find . -name "*.{cc,hh}" -exec sed -i 's/\"types.hh\"/\"types\/types.hh\"/' {} +
```
the source files under sstables include "types.hh", which is
indeed the one located under "sstables", so include "sstables/types.hh"
instea, so it's more explicit.

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
A follow up for the patch for #7611. This change was requested
during review and moved out of #7611 to reduce its scope.
The patch switches UUID_gen API from using plain integers to
hold time units to units from std::chrono.
For one, we plan to switch the entire code base to std::chrono units,
to ensure type safety. Secondly, using std::chrono units allows to
increase code reuse with template metaprogramming and remove a few
of UUID_gen functions that beceme redundant as a result.
* switch get_time_UUID(), unix_timestamp(), get_time_UUID_raw(), switch
min_time_UUID(), max_time_UUID(), create_time_safe() to
std::chrono
* remove unused variant of from_unix_timestamp()
* remove unused get_time_UUID_bytes(), create_time_unsafe(),
redundant get_adjusted_timestamp()
* inline get_raw_UUID_bytes()
* collapse to similar implementations of get_time_UUID()
* switch internal constants to std::chrono
* remove unnecessary unique_ptr from UUID_gen::_instance

1. Move tests to test (using singular seems to be a convention
in the rest of the code base)
2. Move boost tests to test/boost, other
(non-boost) unit tests to test/unit, tests which are
expected to be run manually to test/manual.
Update configure.py and test.py with new paths to tests.
