Does this make the enum forced into a 64-bit integer type?
Yes, the rtems_record_event variable is 64 bit.

The byte order may depend on the architecture of the CPU that
generates the trace, right?
Yes. It can depend on architecture as well.

Is the rtems_record_event in a stream 64-bits?
Yes.
Why do you think it is 64-bits?
To figure out the size of a type you can use GDB:
gdb ./build/misc/rtems-record
[...]
Reading symbols from ./build/misc/rtems-record...
(gdb) p sizeof(rtems_record_event)
$1 = 4
(gdb)
I am really stuck here. I am trying every possible way but only one
variable is printing the wrong value in babeltrace.
I think you rely to much on trial and error.
