Fix: OOT lttng_logger tracepoint not visible with signed kernels

For the same reason as commit dd8d5afb3fabf853cb4c88c0a1a97f470090fe20,
the lttng_logger event was not working on signed kernels with non-signed
lttng modules.

Rename LTTng instrumentation macros

Since LTTng instrumentation macros have a different layout than the
Linux kernel TRACE_EVENT macros, privatize the name.

Here is the mapping:

DECLARE_EVENT_CLASS -> LTTNG_TRACEPOINT_EVENT_CLASS
DEFINE_EVENT -> LTTNG_TRACEPOINT_EVENT_INSTANCE
TRACE_EVENT -> LTTNG_TRACEPOINT_EVENT
TRACE_EVENT_CONDITION -> LTTNG_TRACEPOINT_EVENT_CONDITION
DEFINE_EVENT_CONDITION -> LTTNG_TRACEPOINT_EVENT_INSTANCE_CONDITION
TRACE_EVENT_MAP -> LTTNG_TRACEPOINT_EVENT_MAP
DEFINE_EVENT_MAP -> LTTNG_TRACEPOINT_EVENT_INSTANCE_MAP

LTTNG_V4L2_TRACEPOINT_EVENT -> LTTNG_TRACEPOINT_EVENT_V4L2
DEFINE_WRITEBACK_WORK_EVENT ->
LTTNG_TRACEPOINT_EVENT_WRITEBACK_WORK_INSTANCE
DEFINE_WBC_EVENT -> LTTNG_TRACEPOINT_EVENT_WBC_INSTANCE

DEFINE_EVENT_NOARGS -> LTTNG_TRACEPOINT_EVENT_INSTANCE_NOARGS
TRACE_EVENT_FLAGS -> REMOVE

LTTNG_DECLARE_EVENT_CLASS -> LTTNG_TRACEPOINT_EVENT_CLASS_CODE
LTTNG_DECLARE_EVENT_CLASS_NOARGS ->
LTTNG_TRACEPOINT_EVENT_CLASS_CODE_NOARGS
LTTNG_TRACE_EVENT -> LTTNG_TRACEPOINT_EVENT_CODE

TRACE_EVENT_MAP_NOARGS -> LTTNG_TRACEPOINT_EVENT_MAP_NOARGS
DECLARE_EVENT_CLASS_NOARGS -> LTTNG_TRACEPOINT_EVENT_CLASS_NOARGS

DEFINE_EVENT_MAP_NOARGS -> LTTNG_TRACEPOINT_EVENT_INSTANCE_MAP_NOARGS

DEFINE_EVENT_PRINT -> LTTNG_TRACEPOINT_EVENT_INSTANCE_PRINT
DEFINE_EVENT_PRINT_MAP -> LTTNG_TRACEPOINT_EVENT_INSTANCE_PRINT_MAP

DEFINE_EVENT_CONDITION_MAP ->
LTTNG_TRACEPOINT_EVENT_INSTANCE_CONDITION_MAP
TRACE_EVENT_CONDITION_MAP -> LTTNG_TRACEPOINT_EVENT_CONDITION_MAP

TRACE_EVENT_NOARGS -> LTTNG_TRACEPOINT_EVENT_NOARGS
TRACE_EVENT_FN_MAP -> LTTNG_TRACEPOINT_EVENT_FN_MAP
TRACE_EVENT_FN -> LTTNG_TRACEPOINT_EVENT_FN
