core: spmc: route SP direct requests to logical secure partitions

Extend the SPMC direct request handling so Logical Secure Partitions
(LSPs) can receive direct requests in addition to regular SPs.

This updates the LSP direct_req() callback to take caller_sp, allowing
the handler to distinguish requests coming from an SP from those coming
through the normal-world path. The SPMC direct request flow is updated to
look up LSP destinations, validate their direct request properties, and
route matching requests to the registered LSP callback.

The test LSP callback is updated accordingly.
