Add max_css_buffer_size to gpu characteristics. In the virtual case, the size of the cycle stats snapshot buffer is constrained by the size of the mempool shared between the guest OS and the RM server, so tools need to find out what is the maximum size allowed. In the native case, we return 0xffffffff to indicate that the buffer size is unbounded (subject to memory availability), in the virtual case we return the size of the mempool. Also collapse native init_cyclestats functions to a single version, as each chip had identical versions of the code.
