[PATCH v7 13/18] [gdb/generic] Get rid of linux-core-thread-data

[Luis Machado <luis.machado@arm.com>]

This struct type seems to have been used in the past as a callback
parameter.  Now it seems that case is no longer true, so we can simplify
things by passing the individual parameters linux_core_thread_data
encapsulates directly to the functions.

This is just a cleanup before the next change.
