Use generic boot loader for rp2040-hal examples

Those examples should be independent of a specific board.
The generic boot loader increases their compatibility.

Use wfi in otherwise empty infinite loops in examples

- Clippy warns about empty loops, https://github.com/rust-lang/rust-clippy/issues/6161
- wfi allows to CPU to save some power

WFI was avoided in examples for fear of ill interactions with debuggers.
However the rp2040 debug port does continue to work, as long as the
relevant clocks are not disabled in SLEEP_EN0/SLEEP_EN1. (By default,
all clocks stay enabled in sleep mode.)

This patch replaces several different workarounds with just calling wfi.

Allow to start multiple state machines in sync (#301 )

* add example of synchronized PIOs

* Synchronize state machines using WAIT IRQ instruction

* Use "irq wait 0" instead of "wait 1 irq 0"

This way, the initial value of the interrupt flag doesn't matter

* Start state machines synchronized without IRQ WAIT instruction

* Improve API
