SDitH Integration (#2586)

* Add AES rekey function for AES128 ECB

Added a new function `OQS_AES128_ECB_rekey` to the liboqs AES API,
which allows re-keying an existing AES key schedule without needing
to allocate a new one. This is particularly useful for SDitH which
performs multiple encryptions under different keys in series.

* Support nested common dependencies in copy_from_upstream.

Allow a common dependency to declare a `common_dep` of its own, so
that a commons can build on each other. A common that only aggregates
other commons in this way no longer has to declare `sources`.

* Add SDitH3 signature family via copy_from_upstream.

Points copy_from_upstream to the SDitH integration branch (still in
fork) and adds the resulting generated code. Everything in this commit
outside scripts/copy_from_upstream/ is machine-generated and is not
intended to be reviewed by hand. Reviewers wanting to see what was
changed relative to upstream SDitH should read those at the fork rather
than the generated tree here.

* Gate SDitH by platform and exempt it from -Werror.

SDitH's reference code uses __uint128_t and GCC/Clang function
attributes, neither of which MSVC provides, so the family is disabled
on Windows and on any 32-bit target. There is also a little-endian
assumption in the code, so it is also restricted to little-endian targets.

The imported code is also not yet free of compiler warnings, so its
targets have COMPILE_WARNING_AS_ERROR turned off to keep those
warnings from blocking CI. This is tracked by
open-quantum-safe/liboqs#2588 and should be removed once the upstream
code is cleaned up.
