Copy files instead of hard-linking on Windows 
Fixes an issue on Windows where when source and build directory are on different drives hard-linking
to files or directory fails as it doesn't work across filesystem boundaries. Note that symlinking is also
not possible because it requires administrator privileges on Windows.

The solution copies the files using the built-in cmake `configure_file(src dest COPYONLY)` command.
As this command only operates on files, if a directory is specified the files will be globbed recursively
and through symlinks.

582f72bf3b Fix linking of generated files in cmake 
If generation of files is turned off, and a file is missing, when
building in tree with cmake, you can end up with the generated file
being turned into a symlink to itself. This will also break any future
attempt at building with make. Fix this by testing if the file exists
prior to attempting to link it.

0ff241a1ea Remove largely useless bit of test log to silence GCC 12 
GCC 12 emits a warning because it thinks `buffer1` is used after having been
freed. The code is correct C because we're only using the value of
`(uintptr_t)buffer1`, not `buffer1`. However, we aren't using the value for
anything useful: it doesn't really matter if an alloc-free-alloc sequence
returns the same address twice. So don't print that bit of information, and
this way we don't need to save the old address.

Fixes #5974.

d99083f7a4 Changelog: remove bugfix entry that's actually a robustness improvement 
If the key agreement or the public key export in
ssl_write_client_key_exchange() fails, the handshake enters a failed state.
The only valid thing you can do in a failed handshake is to abort it, which
calls mbedtls_ssl_handshake_free(), which destroys ecdh_psa_privey. While
it's good hygiene to destroy the key in the function that creates it, it
would have been cleaned up a little later in the normal course of things
anyway, so there wasn't an actual bug.

3e56130fb9 psa_raw_key_agreement: return BUFFER_TOO_SMALL when warranted 
psa_raw_key_agreement() returned PSA_ERROR_INVALID_ARGUMENT instead of
PSA_ERROR_BUFFER_TOO_SMALL when the output buffer was too small for ECDH,
the only algorithm that is currently implemented. Make it return the correct
error code.

The reason for the wrong error code is that ecdh.c returns
MBEDTLS_ERR_ECP_BAD_INPUT_DATA, presumably for similarith with dhm.c. It
might make sense to change ecdh.c to use MBEDTLS_ERR_ECP_BUFFER_TOO_SMALL,
but dhm.c doesn't have an existing BUFFER_TOO_SMALL error. To minimize the
impact of the fix, handle this in the PSA layer.

Fixes #5735.
