vlib: replace macros that resolve to __builtin_bswapnn calls for tcc (#19305)

The tcc compiler does not have __builtin_bswap64, __builtin_bswap32,
and __builtin_bswap16 functions.  The various hton and ntoh macros
resolve down to these functions.  When compiling with tcc, we should
be using the analogous functions from net.conv.
