add 'togglePin' convenience function (#8734)
* add 'togglePin' conveniance function

for AVR and chibios

* drop outmost parantheses

Co-Authored-By: Konstantin Đorđević <vomindoraan@gmail.com>

* toggle pin on avrs

toggle a pin configured as output by writing the corresponding bit to the PIN register

Co-Authored-By: Takeshi ISHII <2170248+mtei@users.noreply.github.com>

* togglepin: add documentation for newly added function

* Update docs/internals_gpio_control.md

Co-Authored-By: Konstantin Đorđević <vomindoraan@gmail.com>

* on AVR: use PORTD to toggle the output

... since not all MCUs support toggling through writing to PIN
