Switch from FasterXML Jackson to Avaje Jsonb (#2503)

## Description

WPILib switched from FasterXML Jackson to Avaje Jsonb for speed reasons
in https://github.com/wpilibsuite/allwpilib/pull/8721. This does the
same for PhotonVision. Some temporary Jackson adapters are present to
allow compatibility with alpha-4 ahead of updating Photon's WPILib
version. A few old backwards compatibility migrations were also dropped
if they were difficult to port to Avaje Jsonb or otherwise complicated
the code.
