[ci] [python-package] Use LightGBM-custom manylinux image for building aarch64 Linux wheels

[jameslamb]

Summary

#5252 introduced the use of PoCL for creating wheels that support LightGBM's OpenCL-based GPU code.

As of that PR, LightGBM has to build PoCL from source on every CI run, which is very slow on QEMU builds (#5252 (comment)).

LightGBM's CI should switch to using a pre-built container image that already has PoCL in it.

Motivation

Reduces CI time.

Reduces risk of CI failures.

Description

@StrikerRUS has already created such an image:

• comment: Build integrated OpenCL Linux wheels #5252 (comment)
• code: https://github.com/guolinke/lightgbm-ci-docker/blob/2f6da56d48db9b730b5db16a854ced74961ca14f/dockers/manylinux2014_aarch64/Dockerfile

How to do this

Note
This should only done by a LightGBM maintainer, on a LightGBM-official branch.

• open a PR in this repo which switches the image URI for the QEMU_multiarch bdist image to the new one built from lightgbm-ci-docker and which removes code from .ci/setup.sh that builds PoCL from source

LightGBM/.vsts-ci.yml

Line 193 in f1d3181

IMAGE_URI="quay.io/pypa/manylinux2014_${ARCH}"

• merge update master with latest changes from dev guolinke/lightgbm-ci-docker#28
