Describe the request

Cache the downloaded Arduino platform

Every time an Action is executed, the platform needs to be downloaded. However, the files downloaded by a single version are almost the same, and they are all huge. We hope to reduce the running time of the Action by caching the platform.

Describe the current behavior
