Add MIMXRT1010_EVK & SEEED_ARCH_MIX (mimxrt) v1.26.1

Hello, I've been starting to use mimxrt chips a bit more and was hoping to assist in creating stubs for them. I generated these from the two boards I've got on hand after loading the official release builds and running stubber installed from directly from GitHub. Is this an appropriate way to submit the generated files? Is there a standard process for generating the generic package for a platform eg micropython-mimxrt-stubs as opposed to a board specific one? Is that something I can help with?
