## 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.

Given that WPILib is nuking their Java tooling, it becomes necessary to
pull said tooling into PV itself. This migrates the
CombinedRuntimeLoader into PV, which should finalize all of the tooling
migration.
