renesas-ra/pin: Reduce footprint of pin structures.

Browse Source 
This commit performs a few minor changes to the structures used to store
board pin information, in order to reduce the impact on the .rodata
section of the firmware of instances of those structures.

The pin objects structure ("machine_pin_obj_t") instead has its QSTR
variable holder changed from "qstr" to "qstr_short_t", and some elements
of that structure have been rearranged to remove enough padding bytes
inside structure elements to let the linker allocate less data for
instances of that structure.
