zonefs: add tracepoints for file operations
Add tracepoints for file I/O operations to aid in debugging of I/O errors
with zonefs.
The added tracepoints are in:
- zonefs_zone_mgmt() for tracing zone management operations
- zonefs_iomap_begin() for tracing regular file I/O
- zonefs_file_dio_append() for tracing zone-append operations
