HAL cleanups & remove example macros (esp-rs#261)

* use Systimer from hal where possible * Remove RTC and clocks macros in favour of hal primitives * Remove system! macro * Remove the timer macro * remove the radio macros * Make utils a single file module for remaining util items * Fix rebase issues * Remove redundant example, update esp-now examples
