psa: Introduce psa/build_info.h
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.
