mb/google/bluey: Make GSC_AP_INT GPIO configurable via Kconfig

Browse source 
This commit introduces a Kconfig option to define the GPIO pin used
for the Google Security Chip (GSC) to Application Processor (AP)
interrupt on the Bluey mainboard.

Previously, the GPIO_GSC_AP_INT was hardcoded to GPIO 34 in
board.h. This change makes it configurable for any future variants
using Qualcomm X1P-42-100 SoC.

BUG=b:404985109
TEST=Successfully built google/bluey with the Qualcomm x1p42100 SoC.
