Description

Use Apple’s implementation of the BLAS on Mac.

Benefits:

• possibly resolve long standing issues reported in the community, that PaddlePaddle freeze on some Mac settings.
• Speedup on Mac, since Accelerate Framework is generally faster than openblas on Apple's platform.

Updates

• 2024-5-23 update:
  our nightly build pipeline has been updated, it's possible to use the package with Apple's BLAS by : pip install --no-cache paddlepaddle==0.0.0 -f https://www.paddlepaddle.org.cn/whl/mac/cpu/develop.html.
  I did a quick test, recognizing 15 random images by using time paddleocr --image_dir images, it shows 25% speedup compared with paddlepaddle with openblas on my mac m1. (paddlepaddle using accelerate framework V.S. paddlepaddle using openblas: 1m15.297s V.S. 1m34.525s).

• 2024-5-21 update:
  The required CI has turned green, so I think we can go ahead and merge this PR. Meanwhile, we should wait for feedback to see if it resolves the PaddlePaddle freeze on some Mac settings.

• 2024-5-20 update:
  I can successfully build the package on my mac m1 using command:

cmake -S . -B build-ninja -GNinja -DPY_VERSION=3.9 -DWITH_GPU=OFF -DWITH_TESTING=OFF -DWITH_AVX=OFF -DWITH_ARM=ON -DCMAKE_BUILD_TYPE=Release
cmake --build build-ninja

and successfully run the script in #63344, but building the package with test cases failed on CI pipeline : PR-CI-Mac-Python3.
