Description

Pcard-78266

This PR is based on #59513 and #59518

• support type-promotion mechanism for static-mode APIs. This is happened when we call Block.append_op
• support FLOAT type promotion of Tensor-Tensor for following operaters: +(elementwise_add) / -(elementwise_sub) / *(elementwise_mul) / where in static mode.

From this PR these operators will meet commutative law (currently, only for FLOAT type)，instead of align to former tensor. For example:

>>> paddle.enable_static()
>>> a = paddle.randn((2,3), dtype='float32')
>>> b = paddle.randn((2,3), dtype='float64')
>>> out = a + b

# Before, dtype of out would be same to the former one, i.e. a
>>> out
var tmp_1 : LOD_TENSOR.shape(2, 3).dtype(float32).stop_gradient(True)


# Now, dtype will be promote to float64
>>> out
var tmp_1 : LOD_TENSOR.shape(2, 3).dtype(float64).stop_gradient(True)
