* initial gpio layer * move temlplate.c to template.c.example in preparing to applications.mk rework * separate arduino layer * separate flipper_hal.x * prepare to switch applications on v2 core gpio api * swithch applications to v2 gpio api * gpio api for local target * better gpio_disable handling * remove pwm functions from local target * inline gpio funcs * common function to init all api's * fix local example blink * move delay us to hal api folder * move pwm_set/pwm_stop to hal api folder * update applications to use hal pwm api * remove gpio mode case warning * add speaker demo to build Co-authored-by: DrZlo13 <who.just.the.doctor@gmail.com>
