[quant] Enable quantization for wav2letter

Summary:
Also added annotation support for conv1d_relu and conv1d in XNNPACKQuantizer, the quantized results still
matches fx quant path (didn't quantize conv1d) so tests are not disabled

Test Plan: with-proxy buck2 run executorch/examples/quantization:example -- -m=w2l --verify
