tracing: Fixes for v6.19

tracing fixes for v6.19:

- Add Documentation/core-api/tracepoint.rst to TRACING in MAINTAINERS file

Updates to the tracepoint.rst document should be reviewed by the tracing maintainers.

- Fix warning triggered by perf attaching to synthetic events

The synthetic events do not add a function to be registered when perf attaches to them. This causes a warning when perf registers a synthetic event and passes a NULL pointer to the tracepoint register function. Ideally synthetic events should be updated to work with perf, but as that's a feature and not a bug fix, simply now return -ENODEV when perf tries to register an event that has a NULL pointer for its function. This no longer causes a kernel warning and simply causes the perf code to fail with an error message.

- Fix 32bit overflow in option flag test

The option's flags changed from 32 bits in size to 64 bits in size. Fix one of the places that shift 1 by the option bit number to to be 1ULL.

- Fix the output of printing the direct jmp functions

The enabled_functions that shows how functions are being attached by ftrace wasn't updated to accommodate the new direct jmp trampolines that set the LSB of the pointer, and outputs garbage. Update the output to handle the direct jmp trampolines.
