17a5fb2dce ttl: Remove error-prone sync() calls
These methods are problematic, as with DMA in the picture, the
timestamp member variables did not necessarily reflect the last
submitted event timestamp (see GitHub #1113).

sync() is only very rarely used in typical experimental code, so
the methods are removed without a transition period.
Core.wait_until() can be used to busy-wait for a specified RTIO
timestamp value on the core device CPU instead.

cbfbe24d7a ttl: Remove broken TTLClockGen.sync
The code currently doesn't compile because of a typo in the timestamp
field name. However, tracking event timestamps in software is
problematic anyway (e.g. with DMA, see GitHub #1113), so just remove
`sync()` altogether.

RIDCounter was moved to its own module, as it isn't really

expiry in smoltcp (with its 3 seconds timeout before a discovery
