Botond Dénes 885cb2af07 utils/rjson: include tasklocal backtrace in rapidjson assert error message ...

Currently, the error message on a failed RAPIDJSON_ASSERT() is this:

    rjson::error (JSON error: condition not met: false)

This is printed e.g. when the code processing a json expects an object
but the JSON has a different type. Or if a JSON object is missing an
expected member. This message however is completely inadequate for
determinig what went wrong. Change this to include a task-local
backtrace, like a real assert failure would. The new error looks like
this:

    rjson::error (JSON assertion failed on condition '{}' at: libseastar.so+0x56dede 0x2bde95e 0x2cc18f3 0x2cf092d 0x2d2316b libseastar.so+0x46b623)

Closes scylladb/scylladb#18101
