Remove cryptography related files and a few utility header files that are shared between Mbed TLS and Mbed Crypto. Mbed TLS will use an Mbed Crypto sourced version of each of these header files in order to ease the maintenance burden of both libraries, and to make it easier to keep Mbed TLS and Mbed Crypto in sync. As part of removing cryptography related files, tell Doxygen to source information from the removed the headers, so that it will consider them for inclusion within Doxygen output. Later, as part of the Mbed TLS 3.0 (API breaking version), we'll restructure the organization of the 3 libraries a bit, to move some things out of Mbed Crypto that don't belong there. Candidates of not belonging in Mbed Crypto, but are in libmbedcrypto.so for legacy reasons: - asn1.h - asn1write.h - base64.h - memory_buffer_alloc.h - platform.h - platform_time.h - platform_util.h - threading.h - timing.h - version.h
