feat: supports custom prepare build script

[jizhuozhi]

Ⅰ. Describe what this PR did

Nowadays, if some plugin has additional dependencies need to be installed, developer may change the builder Dockerfile directly, but it's not healthy for long time maintaining.

This PR will support custom prepare build script for each plugin.

默认脚本是不是可以放在.buildrc里，和go保持一致

[007gzs]

The action also needs to be updated accordingly:

higress/.github/workflows/build-and-push-wasm-plugin-image.yaml

Line 133 in aee37c5

cd /workspace/plugins/wasm-rust/extensions/${PLUGIN_NAME}

昨天看了下，gcc那些依赖是ai-data-masking项目里的正则库依赖的，不是一个通用依赖

是的，我的意思是要在这里增加支持 prepare 脚本的逻辑

[007gzs]

参考这里

higress/.github/workflows/build-and-push-wasm-plugin-image.yaml

Lines 111 to 117 in aee37c5

	cd ${{ github.workspace }}/plugins/wasm-${PLUGIN_TYPE}/extensions/${PLUGIN_NAME}
	if [ -f ./.buildrc ]; then
	echo 'Found .buildrc file, sourcing it...'
	. ./.buildrc
	else
	echo '.buildrc file not found'
	fi

[007gzs]

go也没有修改 prepare 脚本的逻辑把，rust和go可以统一固定为插件目录下的 .buildrc

[jizhuozhi]

改成.buildrc了
