rp2: Refactor to not use pico-sdk alarm pool functions for sleeping.
The best_effort_wfe_or_timeout() and sleep_us() pico-sdk functions use the
pico-sdk alarm pool internally, and that has a bug.
Some usages inside pico-sdk (notably multicore_lockout_start_blocking())
will still end up calling best_effort_wfe_or_timeout(), although usually
with "end_of_time" as the timeout value so it should avoid any alarm pool
race conditions.
