@feifei-111 之前的方案会有什么问题？Tensor.name 不符合预期么？

如果两个输入是同一个tensor，组的program会不一致，这个导致sot里面没办法复用之前的program，因为sot希望能直接绕过动转静的cache拿到program。现在会对输入的tensor重命名，这样生成的program就没问题了

原来的Tensor.name无法处理同一个Tensor绑定了Program中两个名字的情况。现在是可以兼容所有的情况的。

消除重复，这个可以被 ShareTensorsIntoScope 复用。

删除掉没用的：_replace_value_with_input_spec

写成函数式：
map(lambda x: x.desct.name, self.inputs)

Description
fix error when using same tensor as inputs in one call
---- wrong program created, when case like:
t = paddle.to_tensor(1)
f(t, t)
fix bugs in jit.save, when program_cache is not empty, jit.save might save a wrong program when input_spec is given
