[FL-1911] FuriHal: i2c refactoring (#847)
* Project: fix release build, replace asserts with checks.
* FuriHal: i2c refactoring, new bus access model, flexible bus gpio configuration.
* FuriHal: set i2c pins to high on detach.
* FuriHal: more i2c bus events, put bus under reset when not used, move bus enable/disable routine to bus handler.
* FuriHal: fix i2c deadlock in power api, add external i2c handle.
