The PSA cryptography repository is based to
start with on the PSA cryptography implementation
in Mbed TLS but with a different directority
structure, build system and build configuration.
The build-time configuration information in the
PSA cryptography repository is psa/build_info.h.
This commit introduces this file in Mbed TLS to
be used in place of mbedtls/build_info.h (but
basically just an alias to it) in PSA headers.
This is to ease the update of the PSA cryptography
repository.

TLS uses it to derive the session secret. The algorithm takes a serialized
point in an uncompressed form, extracts the X coordinate and computes
SHA256 of it. It is only expected to work with P-256.
Fixes#5978.

The PSA max hash size has to be 64 if SHA512 or
SHA384 is supported by the library or an
accelerator, not just in case of the library.

Although checking if the key was symmetric was correct, its easier to
read if we just check the block length is not zero before we use it in a
division.

If PSA_CIPHER_ENCRYPT_OUTPUT_SIZE was called on a non symmetric key,
then a divide by zero could happen, as PSA_CIPHER_BLOCK_LENGTH will
return 0 for such a key, and PSA_ROUND_UP_TO_MULTIPLE will divide by the
block length.

Also remove preprocessor logic for MBEDTLS_CONFIG_FILE, since
build_info.h alreadyy handles it.

Due to repeated calls to PSA_AEAD_NONCE_LENGTH, which in turn calls
PSA_ALG_AEAD_WITH_DEFAULT_LENGTH_TAG several times, some macros updated
in this PR expanded to over 6000 characters, more than the 4095 that ISO
C99 compilers are guaranteed to support.

Where a change was necessary, the new documentation was copied from the
PSA Crypto API spec exactly, with the exception of PSA_AEAD_TAG_LENGTH,
which needed some adjustment.

psa_aead_generate_nonce() could generate a nonce of up to 13 bytes,
depending on the inputs to psa_aead_set_lengths().

In Doxygen documentation, use \c rather than \p when discussing
something that isn't a parameter of the current macro or function.
Where needed, explain what the thing is.

This brings them in line with PSA Crypto API 1.0.0
PSA_ALG_AEAD_WITH_DEFAULT_TAG_LENGTH -> PSA_ALG_AEAD_WITH_DEFAULT_LENGTH_TAG
PSA_ALG_AEAD_WITH_TAG_LENGTH -> PSA_ALG_AEAD_WITH_SHORTENED_TAG

This commit defines the following new macros added to the PSA Crypto API
between versions 1.0 beta 3 and 1.0.0 final:
PSA_AEAD_NONCE_LENGTH
PSA_AEAD_NONCE_MAX_SIZE
PSA_CIPHER_IV_LENGTH
PSA_CIPHER_IV_MAX_SIZE

As a result, the copyright of contributors other than Arm is now
acknowledged, and the years of publishing are no longer tracked in the
source files.
Also remove the now-redundant lines declaring that the files are part of
MbedTLS.
