ANDROID: gic: Add affinity-setting vendor hooks to gic-v3

Add vendor hooks to allow vendor enhancements to GIC v3, specifically
implementation-defined multi-CPU IRQ target affinity setting.

The gic_v3_set_affinity() vendor hook is introduced as a restricted
vendor hook in order to allow trace hook to be called from irq migration
paths.
