Add new hardware request issue template

Hardware support requests currently use the same blank issue form as bug
reports and feature requests, often arriving as one-sentence asks with no
SoC, LoRa IC, or documentation links. This adds a dedicated template that
collects the specific information maintainers need to evaluate and
implement board support.
