[PT2][Quant] Use composble quantizer for embedding + static conv + dynamic (#103116)
Summary:
In this diff we test a module that does a) emedding lookup b) runs 1D
(converted to 2D) conv and c) runs linear on the output of 1d conv.
a is quantized using embedding quantizer.
c is quantized using dynamic quantization.
b is quantized using static quantization.
We compose quantizer from [a, c, b]. Tested it against similar fx config.
Test Plan: test_embedding_conv_linear_quantization
