wasi-nn: do not pretend to support legacy abi in openvino and llamacpp (#4468)

Browse Source 
as tested by core/iwasm/libraries/wasi-nn/test/test_tensorflow.c,
the legacy "wasi_nn" abi uses the number of fp32 for get_output.
because these backends don't implement the abi, bail out explicitly
in build time.

cf.
