…troduces C++23 best practices for coding style that required similar changes in this HAL. It also intoduced a Pin-Port compile time map for very fast I/O (~52 bytes). Other optimizations were made to reduced code size so that this map is essentially free. We now make use of it in the Marlin HAL. Other changes include a GPIO speed compensation bug fix, updating MFL function use to not use deprecated functions, etc.

Description
The latest Arduino core introduces C++23 best practices for coding style that required similar changes in this HAL. It also introduced a Pin-Port compile time map for very fast I/O (~52 bytes). Other optimizations were made to reduced code size so that this map is essentially free. We now make use of it in the Marlin HAL. Other changes include a GPIO speed compensation bug fix, updating MFL function use to not use deprecated functions, board name change from 422->V4 for reuse with other boards in the V4.x.x series, etc.
