oras https_proxy issue 7006 and Support CherryBa M1 board

[IsMrX]

Description

Commit 1:

If you encounter some network reasons that cause the download speed of resources on github and apt source stations to be very slow or fail, maybe we can use the system network proxy to solve it. The latest version supports the network proxy configured by the system environment variable https_proxy. This commit solves the problem that the https_proxy system network proxy configured by oras pull is not effective.

I suggest to split PR into two and I think using HTTPS_PROXY or perhaps ORAS_PROXY would be better? No need to export, but suggest passing it as a build parameter, same as others to preserve code styling.

我建议将 PR 一分为二，我认为使用 HTTPS_PROXY 或者 ORAS_PROXY 会更好？无需导出，但建议将其作为 build 参数传递，与其他参数相同，以保留代码样式。

Thank you for your review. I think using it as a build parameter will raise its threshold, because I have met many partners who don't know how to use build parameters. HTTPS_PROXY as a network proxy system environment variable will lower the threshold for use. As mentioned in the issue. His network environment requires the system to mount the proxy in order to happily download apt resources and github resources. In this way, he can solve the problem of slow oras downloads.

ORAS_PROXY is perhaps more suitable?

We are well aware documentation is bad and outdated :( ... we do what we can.
