Summary: This change allows for handling the in-memory data associated with the FDR mode implementation through the new `__xray_log_process_buffers` API. With this change, we can now allow users to process the data in-memory of the process instead of through writing files. This for example allows users to stream the data of the FDR logging implementation through network sockets, or through other mechanisms instead of saving them to local files. We introduce an FDR-specific flag, for "no_file_flush" which lets the flushing logic skip opening/writing to files. This option can be defaulted to `true` when building the compiler-rt XRay runtime through the `XRAY_FDR_OPTIONS` preprocessor macro.
