Refactor fused quantization patterns into quantize pass.

Current Quantize{DotGeneral, Convolution}OpPattern matching takes place after post_quantize,
which may be misleading.
Instead, factor out patterns in a separate file and handle in quantize.cc.

MLIR tests for fused patterns are left in quantize_composite_functions.mlir for
module-level evaluation of functions.
