[API Compatibility No.10] Add parameter alias support for floor_divide_ -part

[CAICAIIs]

Background

Task #76301 No.10 aims to align torch.Tensor.floor_divide_ with paddle.Tensor.floor_divide_. The key requirement is to support PyTorch-style parameter names (other instead of y) to ensure smooth migration for PyTorch users.

Implementation

1. Added @param_two_alias decorator to floor_divide_ function to map:
   • input → x (Paddle API parameter name)
   • other → y (PyTorch API parameter name)
2. Added comprehensive tests to verify parameter alias support:
   • test_floor_divide_inplace_with_y_parameter: Tests using y parameter (Paddle style)
   • test_floor_divide_inplace_with_other_parameter: Tests using other parameter (PyTorch style)
   • test_floor_divide_inplace_with_both_parameters_error: Tests that using both y and other raises TypeError

Example Usage

After this PR, both PyTorch and Paddle styles work:

import paddle
x = paddle.to_tensor([6, 12, 18])
y = paddle.to_tensor([2, 3, 6])
# PyTorch style (now supported)
x.floor_divide_(other=y)
# Paddle style (still works)
x.floor_divide_(y)

Changes

• python/paddle/tensor/math.py: Added @param_two_alias decorator to floor_divide_ function
• test/legacy_test/test_inplace.py: Added three test methods for parameter alias support

Fixes

• Fixes 【启航计划】PaddlePaddle API兼容性增强 #76301 task 10

floor_divide_ 采用C++下沉方式，但是下沉机制还有点问题。预计年后才能开展开发。
