Clarified comments about the cortex_m::asm::delay functionality in al… (#3064)

* Clarified comments about the cortex_m::asm::delay functionality in all multiprio.rs examples

* fixed formatting

* Changed to using embassy_time::block_for()

* removed my formatting scripts

* specify embassy_time::Duration
