mspm0: add mspm0h321x support

This also changes selection of GPIO interrupt type to be calculated by the buildscript. H321x is yet another exception with GPIOB being a physical interrupt rather than part of an interrupt group.

H3215/6 are true 5V parts. I wonder if that is a first for an embassy hal
