Description
增加XPU下面的
quantize_linear以及dequantize_linear算子。受执行器的某些特殊限制，参考GPU和CPU的实现，增加了两个辅助的没有什么实际意义的算子。当前算子会忽略
qmin、bit_length等等参数。其原因有若干个，例如，python/paddle/nn/quant/format.py的调用入口只传了较少的参数，以及参考GPU和CPU的代码，中间若干层的调用中，会把这些参数逐渐都扔掉（即，不往下传）。此外，经过和业务方讨论，only_observer和round_type也只支持了默认值。此外，不支持
!is_test的情况，等以后有需求了再考虑补充。
