[PATCH v8 21/25] target/tricore: call plugin trap callbacks

[Julian Ganz <neither@nut.email>]

We recently introduced API for registering callbacks for trap related
events as well as the corresponding hook functions. Due to differences
between architectures, the latter need to be called from target specific
code.

This change places an exception hook for TriCore targets. Interrupts are
not implemented for this target and it has no host calls.
