s3:smbprofile: rewrite the internal macros

We now autogenerate a lot of code using
SMBPROFILE_STATS_ALL_SECTIONS macro which expands to
different SMBPROFILE_STATS_{COUNT,BASIC,BYTES,IOBYTES} macros.

This also allows async profiling using:

   struct mystate {
       ...

       SMBPROFILE_BASIC_ASYNC_STATE(profile_state);
       ...
   };

   ...

   SMBPROFILE_BASIC_ASYNC_START(SMB2_negotiate, profile_p, mystate->profile_state);

   ...

   SMBPROFILE_BYTES_ASYNC_SET_IDLE(mystate->profile_state);

   ...

   SMBPROFILE_BYTES_ASYNC_SET_BUSY(mystate->profile_state);

   ...

   SMBPROFILE_BASIC_ASYNC_END(mystate->profile_state);

The current START_PROFILE*()/END_PROFILE*() are implemented as legacy wrappers.
