Adds sof_ipc4_create_debug_slot_debugfs_node() -function for mapping
an SOF Intel ipc4 debug window slot as debugfs file. The actual slot
is specified with slot_type parameter that are defined in
include/sound/sof/ipc4/header.h and the slot is found with
sof_ipc4_find_debug_slot_offset_by_type(). It also takes the
data_offset parameter that specifies where the payload data in the
slot begins. The portion that is mapped to the debugfs file is
everything after the offset. The last parameter is the name of the
file.

Remove ipc4-telemetry.[ch] and use sof_ipc4_create_debug_slot_debugfs_node()
instead for mapping "exception" debugfs file. In running system the
SOF_IPC4_DEBUG_SLOT_TELEMETRY is used for telemetry data, but if configured,
Zephyr exception data is dumped in the same debug window slot, right after
the separator word.
