Set pKVM to enabled in /misc on A0 chips

Browse source 
pKVM provides a workaround for A0 hardware issue. Signal to tests that
an A0 device should not be run without it by enabling it in /misc on
first boot. We only do this on debug builds.

Bug: 266183966
Test: flash, boot, reboot to bootloader, check 'fastboot oem pkvm'
