ad9910: rewire io_delay tuning
...
This now reliably locates the SYNC_CLK-IO_UPDATE edge by doing two
scans at different delays between start and stop IO_UPDATE.
It also works well when one delay is very close to the edge.
And it correctly identifies which (start or stop) pulse hit or crossed
the SYNC_CLK edge.

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.

This commit adds support for injecting initial backing state into
experiments via the device database and sets initial backing state where
known.
