Api hw gpio pwm (#199)
* 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
